HSP43891GC-25

Overview

The HSP43891GC-25 is a high-performance, monolithic 16-bit digital filter manufactured by Harris Corporation. It integrates a switched-capacitor architecture with an on-chip 10-bit analog-to-digital converter and a 16-bit digital-to-analog converter within a single ceramic package. The device operates with a maximum clock frequency of 25 MHz and requires a single +5V power supply. Designed for precision signal processing, it features low power consumption modes and supports external data bus widths of 16 bits with output data bus widths of 24 bits. The component is housed in a CPGA84 package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates a complete 16-bit digital filter system including ADC and DAC components
• Utilizes switched-capacitor technology for precise signal filtering
• Supports low power operation modes for energy efficiency
• Features a robust ceramic metal-sealed cofired package for durability

Applications

• Precision instrumentation requiring high-resolution signal conditioning
• Industrial control systems utilizing digital filtering
• Communication equipment needing stable analog-to-digital conversion

Procurement Notes

Verify the specific suffix 'GC' against manufacturer documentation to confirm pinout compatibility and thermal specifications. Ensure that the required 25 MHz clock signal meets the timing requirements specified in the official datasheet. Confirm that the operating environment stays within the -40°C to +85°C range to maintain performance integrity.

Selection Notes

Select this component when a monolithic solution combining filtering and conversion is required. Compare the 16-bit resolution and 25 MHz clock speed against alternative discrete solutions to evaluate space and complexity savings. Verify that the CPGA84 package footprint fits the target PCB layout constraints.

Part Context

This part belongs to the HSP43xxx series of digital filters from Harris Corporation. These devices were designed to simplify the implementation of complex analog filtering functions using digital techniques. The series typically offers various clock speed options and package configurations to suit different performance and size requirements.

Replacement Considerations

Consult official Harris or Intersil (now Renesas) cross-reference lists for verified equivalents. Generic switched-capacitor filters may not match the integrated ADC/DAC functionality without additional external circuitry.
