HI1-674AKD-5

Analog To Digital Converters (ADC) Overview

The HI1-674AKD-5 is a complete 12-bit Analog-to-Digital Converter (ADC) manufactured by Renesas Electronics Corporation. It utilizes Successive Approximation Register (SAR) architecture and features two single-ended analog inputs within a 28-lead Side Brazed Dual In-Line Package (SBDIP). The device integrates a +10V reference, clock oscillator, and three-state digital outputs for microprocessor interfacing. It operates with ±12V to ±15V analog supplies and a +5V logic supply. The maximum conversion time is 15µs, supporting full 8-bit, 12-bit, or 16-bit bus interfaces.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 12-bit SAR ADC with internal +10V reference and clock
• Maximum conversion time of 15µs at 40k samples per second
• Three-state parallel data output compatible with 8/12/16-bit buses
• Hermetic 28-lead SBDIP package with gold termination finish

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 component authenticity through authorized channels as the part may be subject to obsolescence notices. Confirm RoHS compliance status based on specific manufacturing lot dates, as older stock may not meet current environmental standards. Ensure proper handling procedures are followed for hermetic ceramic packages during installation.

Analog To Digital Converters (ADC) Selection Notes

Select this model when a fast 12-bit conversion speed of 15µs is required compared to the slower HI-574A variant. The 'K' suffix indicates a tighter linearity specification of ±0.5 LSB. The 'D' suffix denotes the side-brazed hermetic package suitable for harsh environments. Verify that the application supports the required ±12V to ±15V analog supply rails.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74 family of complete A/D converters. It shares architectural similarities with the HI-574A but offers faster conversion speeds. The manufacturer recommends considering the ISL263XX and ISL267XX families as potential substitute products for new designs due to evolving product lines.

Analog To Digital Converters (ADC) Replacement Considerations

Public documentation identifies the ISL263XX and ISL267XX families as possible substitute products. Cross-reference pinouts and timing specifications carefully before implementation.
