Overview
The AD574AJDZ is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This integrated circuit is part of the AD574A series, which is known for its high precision and reliability. The AD574AJDZ integrates all analog and digital functions on a single chip, utilizing Analog Devices' Bipolar/I2L process. This design minimizes offset, linearity, and scaling errors through active laser-trimming of thin-film resistors and uses an implanted buried Zener for the voltage reference, ensuring low noise and low drift.
