HI1-674ASD-2

Analog To Digital Converters (ADC) Overview

The HI1-674ASD-2 is a complete 12-bit analog-to-digital converter manufactured by Intersil. It features a successive approximation architecture with two input channels and an integrated reference and clock. The device supports full 8-bit, 12-bit, or 16-bit microprocessor bus interfaces. It is housed in a 28-CDIP package with a bus access time of less than 500 nanoseconds.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a 12-bit A/D converter with built-in reference and clock circuitry
• Supports flexible microprocessor bus interfacing for 8-bit, 12-bit, or 16-bit configurations
• Features a successive approximation conversion architecture

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-resolution data acquisition
• Precision measurement instrumentation
• Data acquisition modules with microprocessor integration

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SD' against official Intersil documentation to confirm pinout and electrical characteristics. Ensure the component matches the 28-CDIP through-hole package specification. Cross-reference the datasheet revision to confirm compatibility with target system voltage levels and interface timing requirements before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a standalone 12-bit ADC with integrated reference and clock is required. It is suitable for applications needing direct microprocessor connection without external logic. Consider the 28-CDIP package for through-hole mounting needs. Evaluate the bus access time against system speed requirements.

Analog To Digital Converters (ADC) Part Context

This part belongs to the HI1 series of complete analog-to-digital converters. It represents Intersil's solution for integrating conversion, reference, and clock functions into a single monolithic device. The series is designed for ease of use in microprocessor-based systems, reducing component count and board space compared to discrete solutions.

Analog To Digital Converters (ADC) Replacement Considerations

Consult Intersil (now Renesas) official substitution guides for verified replacements. Generic ADCs may lack the integrated reference or specific bus interface compatibility.
