HI1-574ALD-5

Analog To Digital Converters (ADC) Overview

The HI1-574ALD-5 is a 12-bit analog-to-digital converter (ADC) manufactured by Harris Corporation, part of the HI-574 family. It utilizes Successive Approximation Register (SAR) architecture to convert analog signals into digital data with a sampling rate of 40 kSPS. The device features two single-ended inputs and operates with dual power supplies ranging from ±11.4V to ±16.5V for analog circuits and 5V for digital logic. Housed in a 28-pin CDIP package, it supports parallel data output and includes optional address selection capabilities.
