HI1-674AJD-5

Analog To Digital Converters (ADC) Overview

The HI1-674AJD-5 is a 12-bit analog-to-digital converter manufactured by Renesas Electronics Corporation, originally part of the Harris Semiconductor portfolio. It utilizes a Successive Approximation Register (SAR) architecture to provide high-speed conversion with a sampling rate of 40 kSPS. The device features two single-ended inputs and operates with dual power supplies ranging from ±11.4V to ±16.5V for analog circuits and 5V for digital logic. Packaged in a 28-pin ceramic DIP (CDIP), it integrates an internal reference and clock, supporting parallel data output.

Analog To Digital Converters (ADC) Procurement Notes

The HI1-674AJD-5 is listed as obsolete or end-of-life by the manufacturer. Verification of component authenticity is critical due to potential availability through third-party distributors. Confirm RoHS compliance status, which may be non-compliant depending on the manufacturing date, and verify package integrity before integration into new designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit SAR ADC with integrated reference and clock is required in a through-hole DIP package. Ensure the design supports dual analog supply rails up to ±16.5V. For modern replacements, consider current Renesas HI-574 series variants or equivalent 12-bit SAR ADCs with similar pinouts and performance specifications.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-574/HI-674 family of complete 12-bit ADCs. The 'J' suffix indicates a military-grade temperature range (0°C to 75°C) and ceramic package, while 'D' denotes the 28-pin CDIP form factor. The '5' typically specifies the 5V digital supply variant.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed direct substitutes include the HI-574AJD-5 and HI-574AJD-5Z. Verify pin compatibility and electrical parameters against the specific datasheet revision before substitution.
