HI3-574AKN-5Z

Analog To Digital Converters (ADC) Overview

The HI3-574AKN-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, clock oscillator, and three-state digital outputs. The device supports full 8-bit, 12-bit, or 16-bit microprocessor bus interfaces with a maximum bus access time of 150ns. It operates on supply voltages of +5V logic and ±12V to ±15V analog supplies, consuming approximately 385mW at ±12V. The component is housed in a 28-lead Plastic Dual In-Line Package (PDIP) and is rated for operation within a temperature range of 0°C to +75°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with internal +10V reference and clock

• Four selectable input ranges: 0 to +10V, 0 to +20V, ±5V, and ±10V
• 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 provides the 'Z' suffix variant, which indicates Pb-free packaging compliant with RoHS standards. Confirm the package type is 28-lead PDIP, as other suffixes denote different physical packages such as SBDIP. Ensure the ordering suffix matches the required accuracy grade ('K' for ±0.5 LSB INL).

Analog To Digital Converters (ADC) Selection Notes

Select the HI3-574AKN-5Z when a ±0.5 LSB Integral Nonlinearity (INL) specification is required. Choose this part over the 'J' suffix variant if tighter linearity performance is necessary. Verify that the application environment remains within the 0°C to +75°C operating temperature range specified for this package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74A family of complete 12-bit A/D converters. It is functionally compatible with industry-standard devices like the AD574A and MX574A. The manufacturer notes that this specific product is not recommended for new designs and suggests considering the ISL263XX and ISL267XX families as potential substitutes.

Analog To Digital Converters (ADC) Replacement Considerations

Public confirmed substitute part numbers include MX574AKEWI+ and AD574AKD.
