ANALOG DEVICES Low Power 16-/24-Bit Sigma-Delta ADC AD7788/AD7789 handbook
The AD7788 and AD7789 are low‑power, low‑noise sigma‑delta analog‑to‑digital converters designed for precision measurement applications such as smart transmitters, battery monitors, and weighing scales. The devices operate from a single supply and include an internal clock, offering simultaneous 50 Hz/60 Hz line‑frequency rejection.
Key features include 16‑bit (AD7788) or 24‑bit (AD7789) resolution, 1 pA power‑down current, a 10‑lead MSOP package, and a 3‑wire serial interface compatible with SPI, QSPI, Microwire, and DSP protocols. Detailed specifications, timing characteristics, and pin functions are provided for designers.
