HI1-574AKDB3924-0003

Encoders, Decoders, Converters Overview

The HI1-574AKDB3924-0003 is a 12-bit analog-to-digital converter (ADC) manufactured by Renesas Electronics Corporation, part of the HI-574 series. It utilizes a Successive Approximation Register (SAR) architecture and features two single-ended input channels with a parallel data interface. The device operates on dual power supplies, typically ±11.4V to ±16.5V for analog circuits and 5V for digital logic. Key performance specifications include a sampling rate of 40 kS/s, a differential nonlinearity (DNL) of ±1 LSB, and an integral nonlinearity (INL) of ±0.5 LSB. It supports both external and internal reference voltages and functions within a commercial temperature range of 0°C to +75°C.

Encoders, Decoders, Converters Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status as specific variants may differ. Check for end-of-life notices or obsolescence warnings from Renesas Electronics prior to procurement. Ensure supply chain stability given the component's age and potential discontinuation status in certain markets.

Encoders, Decoders, Converters Selection Notes

Select this component when a 12-bit resolution and 40 kS/s sampling rate are required for single-ended signals. Ensure the design supports parallel interfaces and dual power supply rails. Consider thermal management for the 1W power dissipation. Evaluate alternative packages if surface-mount PLCC-28 is unsuitable for the target PCB layout.

Encoders, Decoders, Converters Part Context

This part belongs to the HI-574 family of high-speed, low-power monolithic A/D converters. The series includes various pin-compatible variants such as the HI1-574AJD-5 and HI1-574AKD-5. These devices were originally developed by Harris Semiconductor before its acquisition by Intersil and subsequently Renesas Electronics. The family is known for its industry-standard parallel interface compatibility.

Encoders, Decoders, Converters Replacement Considerations

Direct replacements include HI1-574AJD-5 and HI1-574AKD-5 from Renesas. Cross-vendor equivalents should be verified for pinout compatibility and electrical parameter alignment. Note that some variants may have different suffixes indicating package type or temperature grade.
