Overview
The AD574ATE/883B is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This component integrates all analog and digital functions on a single chip, utilizing Analog Devices' Bipolar/I2L process. The design minimizes offset, linearity, and scaling errors through active laser-trimming of thin-film resistors at the wafer stage. The voltage reference is based on an implanted buried Zener, ensuring low noise and low drift. The digital side employs I2L logic for the successive-approximation register, control circuitry, and 3-state output buffers.
