The AD7713 is a 24-bit, low-power, loop-powered, signal conditioning ADC with three programmable gain front ends, two differential inputs, and one single-ended high-voltage input.
The AD7713 is a complete analog front-end designed for low-frequency measurement applications. It utilizes a proprietary charge-balancing sigma-delta conversion technique to achieve up to 24 bits of no missing codes performance. The device accepts low-level signals directly from transducers or high-level signals and outputs a serial digital word.
