Part Overview

Description
The MAX1246/MAX1247 are 12-bit data acquisition systems that combine a 4-channel multiplexer, high-bandwidth track/hold, and serial interface with high conversion speed and low power consumption. They operate from a single 2.7V to 3.6V supply (MAX1246) or 2.7V to 5.25V supply (MAX1247). The analog inputs are software configurable for unipolar/bipolar and single-ended/differential operation. The 4-wire serial interface connects directly to SPI/QSPI/MICROWIRE/TMS320-family devices without external logic. The MAX1246/MAX1247 use either the internal clock or an external serial-interface clock to perform successive-approximation analog-to-digital conversions. The MAX1246 has an internal 2.5V reference, while the MAX1247 requires an external reference. Both parts have a reference-buffer amplifier with a 1.5% voltage-adjustment range. They provide a hard-wired SHDN pin and a software-selectable power-down, and can be programmed to automatically shut down at the end of a conversion. Accessing the serial interface automatically powers up the MAX1246/MAX1247, and the quick turn-on time allows them to be shut down between all conversions. This technique can cut supply current to under 60µA at reduced sampling rates. The MAX1246/MAX1247 are available in a 16-pin DIP and a small QSOP that occupies the same board area as an 8-pin SO.

  • 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.

  • 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.

  • 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.

  • Polarity

    Polarity refers to the direction of current flow through an electronic component. It is typically indicated by a plus (+) or minus (-) sign on the component's body. Components with polarity must be connected correctly in a circuit to function properly. For example, a diode will only allow current to flow in one direction, from the positive terminal to the negative terminal. If a diode is connected backwards, it will not conduct current.

  • Sampling Rate

    Sampling rate refers to the number of times per second that an analog signal is measured and converted into a digital signal. It is expressed in Hertz (Hz) and determines the maximum frequency that can be accurately represented in the digital signal. A higher sampling rate results in a more accurate representation of the analog signal, but also increases the amount of data that needs to be processed. The sampling rate must be at least twice the highest frequency component of the analog signal to avoid aliasing, where high-frequency components are incorrectly represented as lower-frequency components.
