HI1-574ATD/883

Analog To Digital Converters (ADC) Overview

The HI1-574ATD/883 is a high-performance, monolithic 12-bit successive approximation register (SAR) analog-to-digital converter (ADC). Manufactured by Intersil and processed in accordance with MIL-STD-883 standards, this component is qualified for QML Class Q military applications. It features a parallel digital interface compatible with microprocessors and operates over an extended temperature range of -55°C to +125°C. The device integrates internal reference capabilities while supporting external references, powered by dual supplies typically at ±15V for analog and 5V for digital sections. Housed in a 28-pin ceramic DIP package, it delivers precise data acquisition with low power dissipation.

Analog To Digital Converters (ADC) Part Context

The HI1-574A series represents the military-grade variant of the standard AD574A ADC family. The '/883' suffix indicates compliance with MIL-STD-883 testing requirements, ensuring suitability for defense and aerospace sectors where standard commercial components are insufficient. Intersil (now part of Renesas) produced these parts to meet specific quality assurance protocols for critical systems.
