HI1-574AJD-5

Analog To Digital Converters (ADC) Overview

The HI1-574AJD-5 is a complete 12-bit Analog-to-Digital Converter (ADC) utilizing Successive Approximation Register (SAR) architecture. It integrates a +10V reference, clock oscillator, and three-state digital outputs within a single unit. The device features a parallel microprocessor interface supporting full 8-bit, 12-bit, or 16-bit bus configurations. It operates with analog supply voltages ranging from ±11.4V to ±16.5V and a digital logic supply of 5V. The component is housed in a 28-lead Small Body Dual In-line Package (SBDIP).

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with internal +10V reference and clock oscillator.
• Flexible microprocessor bus interface supporting 8-bit, 12-bit, and 16-bit modes.
• Three-state data outputs for direct system bus connection.
• Current-mode signal transmission between monolithic dice for low noise performance.

Analog To Digital Converters (ADC) Applications

• Military and industrial data acquisition systems.
• Electronic test and scientific instrumentation.
• Process control systems.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'J' which denotes ±1.0 LSB Integral Non-Linearity (INL) accuracy. Confirm the 'D' suffix indicates the 28-lead SBDIP package type. Check the '-5' suffix for the commercial temperature range of 0°C to +75°C. Ensure compatibility with the required ±12V to ±15V analog supplies and +5V logic voltage.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a 12-bit resolution with ±1.0 LSB linearity error is sufficient. The HI1-574AJD-5 offers a maximum conversion time of 25µs. For applications requiring faster conversion speeds, consider the HI-674A variant. Ensure the design accommodates the dual power supply requirement of ±12V/±15V and +5V logic.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74(A) family of complete 12-bit A/D converters. It utilizes Intersil's Dielectric Isolation process for the bipolar analog die to ensure latch-up freedom and enhanced AC performance. The device combines a bipolar analog section and a CMOS digital section on separate monolithic dice within one package.

Analog To Digital Converters (ADC) Replacement Considerations

Public documentation identifies ISL263XX and ISL267XX families as possible substitute products. Verify pinout and electrical parameter compatibility before substitution.
