ADC121S625 - Micro Power Sampling A/D Converter

Datasheet Summary

Description

The ADC121S625 is a 12-bit, 50 ksps to 200 ksps sampling Analog-to-Digital (A/D) converter that

Features

  • a fully differential, high impedance analog input and an external reference. While best performance is achieved with reference voltage between 500mV and 2.5V, the reference voltage can be varied from 100mV to 2.5V, with a corresponding resolution between 49µV and 1.22mV. The output serial data is binary 2’s complement, and is compatible with several standards, such as SPI™, QSPI™,.
