HI3-574AKN-5

Analog To Digital Converters (ADC) Overview

The HI3-574AKN-5 is a complete 12-bit Analog-to-Digital Converter manufactured by Renesas Electronics Corporation. It utilizes a Successive Approximation Register (SAR) architecture and features two monolithic dice housed in a 28-lead Plastic Dual In-Line Package (PDIP). The device integrates a +10V reference, clock oscillator, and three-state digital outputs for direct microprocessor interfacing. It supports full 8-bit, 12-bit, or 16-bit bus interfaces with a maximum bus access time of 150ns. The component operates on supply voltages ranging from ±12V to ±15V for analog circuits and +5V for logic, ensuring precise conversion performance across the specified temperature range.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with internal +10V reference and clock
• Microprocessor interface supporting 8-bit, 12-bit, or 16-bit data buses
• Guaranteed no missing codes over the operating temperature range
• Low noise current-mode signal transmission between analog and digital dice

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 ordering suffix 'KN' corresponds to the specific package and accuracy grade required. Confirm RoHS compliance status as standard PDIPs may differ from Pb-free variants. Ensure the procurement source provides documentation verifying the ±0.5 LSB Integral Nonlinearity (INL) specification associated with the K suffix.

Analog To Digital Converters (ADC) Selection Notes

Select the HI3-574AKN-5 when a 12-bit resolution with ±0.5 LSB INL accuracy is required for through-hole mounting. This model is suitable for applications needing a complete ADC solution with integrated reference and clock. Compare against the HI3-574AJN-5 if ±1.0 LSB linearity is acceptable, or consider the HI3-674A series if faster conversion times are necessary.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74(A) family of complete 12-bit A/D converters. It shares functional similarities with other industry-standard converters like the AD574A and MX574A but differs in packaging and specific electrical characteristics. The HI3-574AKN-5 specifically denotes the plastic DIP package variant with enhanced linearity specifications compared to the J-grade counterpart.
