HI-574 Datasheet Complete/ 12-Bit A/D Converters with Microprocessor Interface

Manufacturer: Intersil (now Renesas)

General Description

The HI-X74(A) is a complete 12-bit, Analog-to-Digital Converter, including a +10V reference clock, three-state outputs and a digital interface for microprocessor control.

Successive approximation conversion is performed by two monolithic dice housed in a 28 lead package.

Overview

HI-574A, HI-674A, HI-774 August 1997 Complete, 12-Bit A/D Converters with Microprocessor.

Key Features

  • the Intersil Dielectric Isolation process, which provides enhanced AC performance and freedom from latch-up. Custom design of each IC (bipolar analog and CMOS digital) has yielded improved performance over existing versions of this converter. The voltage comparator features high PSRR plus a high speed current-mode latch, and provides precise decisions down to 0.1 LSB of input overdrive. More than 2X reduction in noise has been achieved by using current instead of voltage for transmission of all.
