HI3-674AJN-5

Analog To Digital Converters (ADC) Overview

The HI3-674AJN-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 an integrated +10V reference clock with three-state outputs for direct microprocessor interface. The device supports full 8-bit, 12-bit, or 16-bit bus access times of 150ns maximum. It operates on supply voltages of ±12V to ±15V for analog circuits and +5V for digital logic. 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) Procurement Notes

Verify RoHS compliance status as standard PDIP versions may differ from Pb-Free variants. Confirm package type matches design requirements, as hermetic SBDIP options exist for wider temperature ranges. Check datasheet notes regarding wave solder processing limitations for specific plastic packages.

Analog To Digital Converters (ADC) Selection Notes

Select this model for applications requiring 15µs conversion speed; the HI-574A variant offers 25µs. Ensure power supplies are regulated between ±12V and ±15V for analog rails and +5V for logic. Verify input impedance compatibility, as the device presents 5kΩ for 10V spans and 10kΩ for 20V spans.

Analog To Digital Converters (ADC) Part Context

This part belongs to the HI-X74(A) family, which includes the HI-574A and HI-674A series. These converters utilize monolithic dice housed in a single package, employing current-mode signal transmission between analog and digital sections to reduce noise. The HI3 prefix denotes the commercial temperature grade (0°C to +75°C) in the PDIP package.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet identifies the ISL263XX and ISL267XX families as possible substitute products. Verify pinout and electrical specifications against these alternatives before implementation.
