Part Overview

Description
The MAX9934 is a high-precision, low-voltage, high-side current-sense amplifier designed for bidirectional and unidirectional current measurements in battery-powered portable and laptop devices. It features a low input offset voltage of 10µV (max) and a wide input common-mode voltage range of -0.1V to 5.5V. The MAX9934's precision input specification allows for the use of small sense voltages (typically 10mV full-scale) for minimally invasive current sensing.
The output of the MAX9934 is a current proportional to the input VSENSE and is available in either 25μA/mV or 5μA/mV gain options (GM) with gain accuracy better than 0.25% (max) at 25°C. A chip select (CS) allows multiplexing of several MAX9934 current outputs to a single microcontroller ADC channel. The CS is compatible with 1.8V and 3.3V logic systems.
The MAX9934 operates from a 2.5V to 3.6V VCC supply and draws just 120uA (typ) quiescent current. When powered down (Vcc = 0), RS and RS- draw less than 0.1nA (typ) leakage current to reduce battery load. The MAX9934 is robust and protected from input faults of up to 16V input differential voltage between RS and RS-.

  • Mounting Type

    Mounting Type refers to the method by which an electronic component is attached to a printed circuit board (PCB) or other surface. Common mounting types include: * Through-hole: Component leads are inserted into holes in the PCB and soldered on the other side. * Surface-mount: Component is placed on the surface of the PCB and soldered in place. * Press-fit: Component is pressed into place on the PCB without soldering. * Socket: Component is inserted into a socket on the PCB, allowing for easy replacement. The mounting type is determined by factors such as the component's size, shape, and power requirements.

    Surface Mount
  • Package / Case

    Package / Case refers to the physical housing or enclosure that encapsulates an electronic component. It provides protection, facilitates handling, and enables electrical connections. The package type determines the component's size, shape, pin configuration, and mounting options. Common package types include DIP (dual in-line package), SOIC (small outline integrated circuit), and BGA (ball grid array). The package also influences the component's thermal and electrical performance.

  • Surface Mount
    YES
  • Number of Pins

    Number of Pins: Indicates the number of electrical connections available on the component. These pins are used to connect the component to other components or circuits on a printed circuit board (PCB). The number of pins determines the functionality and connectivity options of the component. It is important to ensure that the component has the correct number of pins for the intended application.

  • Operating Temperature

    Operating Temperature is the range of temperatures at which an electronic component can function properly. It is typically specified in degrees Celsius (°C) and indicates the minimum and maximum temperatures at which the component can operate without experiencing damage or degradation. Operating Temperature is an important parameter to consider when designing electronic circuits, as it ensures that the components will function reliably in the intended operating environment.

  • Part Status

    Part Status is an electronic component parameter that indicates the availability and production status of a component. It is typically used to inform customers about the availability of a component, whether it is in production, end-of-life, or obsolete. Part Status can also provide information about any restrictions or limitations on the component's use, such as whether it is only available for certain applications or if it has been discontinued.

  • Moisture Sensitivity Level (MSL)

    Moisture Sensitivity Level (MSL) is a measure of the susceptibility of a surface mount electronic component to moisture-induced damage during soldering. It is classified into six levels, from 1 (least sensitive) to 6 (most sensitive). MSL is determined by the materials used in the component's construction, including the solderability of its terminals and the presence of moisture-absorbing materials. Components with higher MSL ratings require more stringent handling and storage conditions to prevent moisture absorption and subsequent damage during soldering.

  • Technology

    Technology, in the context of electronic components, refers to the specific manufacturing process and materials used to create the component. It encompasses the semiconductor fabrication techniques, such as the type of transistor used (e.g., MOSFET, BJT), the gate oxide thickness, and the interconnect materials. Technology also includes the packaging type, such as surface mount or through-hole, and the leadframe or substrate material. The technology used impacts the component's performance characteristics, such as speed, power consumption, and reliability.

  • Supply Voltage

    Supply Voltage is the voltage required to power an electronic component. It is typically measured in volts (V) and is specified in the component's datasheet. The supply voltage must be within the specified range for the component to function properly. If the supply voltage is too low, the component may not function at all. If the supply voltage is too high, the component may be damaged.

  • Number of Circuits

    Number of Circuits refers to the number of independent signal paths within an electronic component. It indicates how many separate circuits or channels the component can handle simultaneously. For example, an operational amplifier with a Number of Circuits of 2 can amplify two separate input signals independently. This parameter is crucial for determining the component's functionality and its suitability for specific applications.

  • Operating Supply Current

    Operating Supply Current is the amount of current drawn by an electronic component when it is operating under normal conditions. It is typically measured in milliamps (mA) or microamps (µA). The operating supply current is important because it can affect the power consumption of the component and the overall system. A higher operating supply current will result in higher power consumption, which can lead to overheating and reduced battery life.

  • Input Offset Voltage (Vos)

    Input Offset Voltage (Vos) is a parameter that specifies the voltage difference between the non-inverting and inverting inputs of an operational amplifier (op-amp) when the output voltage is zero. It represents the amount of voltage that must be applied to the inputs to bring the output to zero. Vos is caused by mismatches in the internal transistors of the op-amp and can vary with temperature and other factors. A low Vos is desirable for precision applications where accurate signal processing is required.

  • Bandwidth

    Bandwidth, in the context of electronic components, refers to the range of frequencies over which a component can operate effectively. It is typically measured in Hertz (Hz) and indicates the component's ability to pass signals within a specific frequency range without significant attenuation or distortion. A higher bandwidth indicates a wider range of frequencies that the component can handle, while a lower bandwidth indicates a narrower range. Bandwidth is a crucial parameter for components such as amplifiers, filters, and communication systems, as it determines the frequency range over which they can perform their intended functions.

    1.5 kHz
  • Length

    Length, in the context of electronic components, refers to the physical dimension of a component along its longest axis. It is typically measured in millimeters (mm) or inches (in). Length is a crucial parameter for determining the physical size and space requirements of a component on a printed circuit board (PCB) or other assembly. It also affects the component's electrical characteristics, such as inductance and capacitance, which can be influenced by the length of conductors or traces within the component.
