Product Introduction

Overview

The AD574AKPZ is a 12-bit analog-to-digital converter (ADC) produced by Analog Devices Inc. This integrated circuit is part of the AD574A family, which is known for its high precision and reliability. The AD574AKPZ 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 at the wafer stage. The voltage reference is based on an implanted buried Zener, ensuring low noise and low drift. The digital side of the chip uses I2L logic for the successive-approximation register, control circuitry, and 3-state output buffers.
