The AD7703 LC2MOS 20-Bit A/D Converter features low power and high resolution, and is suitable for use in industrial process control, weighing scales, portable instrumentation, and remote data acquisition applications.
The AD7703 is a 20‑bit, charge‑balancing A/D converter with on‑chip digital filtering, designed for low‑frequency, high‑dynamic‑range measurements such as industrial process control, weigh scales, and portable instrumentation. It features programmable low‑pass filters, flexible serial interfaces, ultralow power consumption, and self‑calibration capabilities.
The document includes functional block diagrams, detailed pin configurations, timing characteristics, power‑supply requirements, and extensive static and dynamic performance specifications, along with calibration procedures and ESD handling guidelines.
| Maximum Output Data Rate | 4 kSPS |
|---|---|
| Standby Power Consumption | 10 µW |
The AD7703 can output data at up to 4 kSPS.
In standby (sleep) mode the device consumes typically 10 µW.
The AD7703 offers an asynchronous UART‑compatible mode and two synchronous modes for interfacing with microcontrollers.
