HI1-574AKD-5

Analog To Digital Converters (ADC) Overview

The HI1-574AKD-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 precision +10V reference voltage source and an internal clock oscillator, eliminating the need for external timing components. It supports full 8-bit, 12-bit, or 16-bit microprocessor bus interfaces with three-state outputs. Electrical specifications include a maximum conversion time of 25µs, operating supply voltages of ±11.4V to ±16.5V for analog circuits and 5V for digital logic, and a commercial operating temperature range of 0°C to +75°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity as this part number may be subject to obsolescence notices. Confirm that the SBDIP package termination finish meets specific soldering requirements for your assembly process. Ensure that design-in documentation accounts for the dual-die construction and current-mode interconnect characteristics when evaluating performance in noisy environments.

Analog To Digital Converters (ADC) Selection Notes

Select the HI1-574AKD-5 for applications requiring high linearity (±0.5 LSB INL) and robust performance in industrial environments. The 'K' suffix denotes tighter linearity specifications compared to the 'J' grade. Ensure the host system provides stable ±12V to ±15V analog supplies and a clean +5V logic rail to maintain specified power supply rejection ratios and conversion accuracy.

Analog To Digital Converters (ADC) Part Context

This component belongs to the HI-X74A family of complete 12-bit A/D converters. It is functionally compatible with industry-standard parts like the AD574A but offers improved AC performance through dielectric isolation and current-mode signal transmission. The HI1-574AKD-5 specifically represents the hermetic ceramic SBDIP variant with enhanced linearity, designed for reliability in demanding conditions.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Designers should consult manufacturer recommendations for potential future products, such as the ISL263XX and ISL267XX families, though these may require circuit redesign due to architectural differences.
