The AD7713 is a 24-bit low power AD converter from Analog Devices, with 3-channel programmable gain front end, which can be used in loop powered (smart) transmitters, RTD transducers, process control and portable industrial instruments.
The AD7713 is a 24‑bit charge‑balancing ADC designed for loop‑powered signal‑conditioning applications. It features three programmable‑gain channels, low‑power operation (typical 3.5 mW), and a bidirectional serial interface for microcontroller integration.
The document includes detailed functional block diagrams, absolute maximum ratings, timing characteristics, and ordering information for PDIP, CERDIP, and SOIC packages, making it a complete reference for designers and engineers.
