AD7794BRU Description
The package or case for this particular electronic component is a 24-TSSOP (0.173, 4.40mm Width), which refers to the size and shape of the chip. This package is commonly used for integrated circuits and offers a compact and efficient design. The operating temperature range for this component is -40°C~105°C, making it suitable for use in a wide range of environments. The peak reflow temperature, measured in degrees Celsius, is 240, indicating the maximum temperature at which the component can be exposed during the manufacturing process. With 1 function and a MUX-ADC configuration, this component is versatile and can be used for a variety of purposes. It has a minimum input voltage requirement of 100mV and utilizes a Sigma-Delta architecture, which is known for its high precision and low noise performance. The supply type is single, meaning it requires a single power source to function. The data interface for this component is SPI and DSP, allowing for efficient communication with other devices. With 1 A/D converter, this component is capable of converting analog signals into digital data for processing.

AD7794BRU Features
Up to 23 effective bits Six differential analog inputs Power supply: 2.7 V to 5.25 V Independent interface power supply Power-down: 1 μA maximum

Analog to Digital Converters - ADC 6Ch Lo Noise Lo Pwr 24B w/ On-Chip Ref
The AD7794/AD7795 are low power, low noise, complete analog front ends for high precision measurement applications. They contain a low noise, 24-/16-bit Σ-Δ ADC with six differential inputs. The on-chip low noise instrumentation amplifier means that signals of small amplitude can be interfaced directly to the ADC. Each device contains a precision, low noise, low drift internal band gap reference, and can also accept up to two external differential references. Other on-chip features include programmable excitation current sources, burnout currents, and a bias voltage generator that is used to set the common-mode voltage of a channel to AVDD/2. The low-side power switch can be used to power down bridge sensors between conversions, minimizing the system’s power consumption. The AD7794/AD7795 can operate with either an internal clock or an external clock. The output data rate from each part can vary from 4.17 Hz to 470 Hz. Both parts operate with a power supply from 2.7 V to 5.25 V. The B-grade parts (AD7794 and AD7795) are specified for a temperature range of −40°C to 105°C while the C-grade part (AD7794) is specified for a temperature range of −40°C to 125°C. They consume a current of 400 μA typical and are housed in a 24-lead TSSOP. Applications Temperature measurement Pressure measurement Weigh scales Strain gage transducers Gas analysis
