HI3-574AJN-5Z

Analog To Digital Converters (ADC) Overview

The HI3-574AJN-5Z is a complete 12-bit Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It utilizes a Successive Approximation Register (SAR) architecture and features an integrated +10V reference and clock oscillator. The device provides three-state digital outputs compatible with 8-bit, 12-bit, or 16-bit microprocessor buses. It operates within a temperature range of 0°C to +75°C and is housed in a 28-lead Plastic Dual In-Line Package (PDIP). This specific part number denotes the Pb-Free version of the standard HI3-574AJN-5.

Analog To Digital Converters (ADC) Feature Summary

• Complete 12-Bit SAR ADC with internal +10V reference and clock
• Microprocessor interface supporting 8-bit, 12-bit, or 16-bit bus widths
• Pb-Free compliant 28-lead PDIP package (E28.6)
• Guaranteed no missing codes over the operating temperature range

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 that the procurement source explicitly confirms the 'Z' suffix indicates Pb-Free compliance for the plastic DIP package. Ensure the component matches the E28.6 package drawing. Confirm the manufacturer is Renesas Electronics Corporation or its authorized predecessor entities, as Intersil was acquired by Renesas.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with ±1 LSB linearity error is required for commercial temperature ranges (0°C to +75°C). Choose the HI3-574AJN-5Z over the HI3-574AKN-5Z if the ±1 LSB accuracy specification is sufficient, as it offers a lower performance tier than the ±0.5 LSB K-grade. Ensure the application supports the required ±12V to ±15V analog supply rails.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74A family, which includes the HI-574A and HI-674A variants. The HI3-574AJN-5Z is the commercial grade, Pb-free plastic version of the HI-574A. It shares the same functional block diagram and pinout with other HI-X74A devices but differs in conversion speed and accuracy grades compared to the HI-674A or higher-grade HI-574A parts.

Analog To Digital Converters (ADC) Replacement Considerations

Public datasheets indicate the ISL263XX and ISL267XX families as possible substitute products. Verify compatibility regarding pinout, supply voltages, and interface logic before substitution.
