Overview

The AD7794/AD7795 are low power, low noise, complete analog front ends designed for high precision measurement applications. They incorporate a low noise 24-bit/16-bit, 6-channel differential input Σ-Δ ADC, along with an on-chip low noise instrumentation amplifier that allows small signals to be applied directly to the ADC. Each device features a precision low noise, low drift internal bandgap voltage reference, and supports up to two external differential references. Additional on-chip features include programmable excitation current sources, burnout current control, and a bias voltage generator that can set the common-mode voltage of any channel to AVDD/2. A low-side power switch can be used to power down bridge sensors between conversions, minimizing overall system power consumption. The AD7794/AD7795 can operate with either an internal or external clock, with output data rates ranging from 4.17 Hz to 470 Hz. Both devices operate from a 2.7 V to 5.25 V supply. Grade B devices (AD7794 and AD7795) are rated for the -40°C to +105°C temperature range, while Grade C devices (AD7794) are rated for -40°C to +125°C. These devices have a typical current consumption of 400 μA and are available in a 24-lead TSSOP package.
