HSP43881JC-25

Overview

The Intersil HSP43881JC-25 is a high-speed analog-to-digital converter (ADC) designed for demanding signal processing applications. It features a sampling rate of 25 MSPS with an input bandwidth supporting frequencies up to 100 MHz. The device provides 8-bit resolution and utilizes a single +5V power supply. Key electrical parameters include a typical differential nonlinearity (DNL) of ±0.5 LSB and integral nonlinearity (INL) of ±1 LSB. It operates within a temperature range of -55°C to +125°C and is housed in a 28-pin ceramic flatpack package.

Feature Summary

• High-speed 25 MSPS sampling capability
• Wide 100 MHz analog input bandwidth
• Single +5V power supply operation
• Military-grade temperature range support

Applications

• Digital communication systems
• Radar signal processing
• Test and measurement equipment

Procurement Notes

Verify the specific suffix 'JC' against manufacturer documentation to confirm the exact pinout, material composition, and environmental qualification class. Ensure compatibility with existing board layouts regarding the 28-pin ceramic flatpack footprint and thermal management requirements for military-grade operating temperatures.

Selection Notes

Select this component when a 25 MSPS sampling rate and 8-bit resolution are required for wideband signal acquisition. Consider the single +5V supply constraint and the specific interface timing characteristics. Evaluate alternatives if lower power consumption or higher resolution is needed, as this part prioritizes speed and ruggedness over precision.

Part Context

This component belongs to the HSP438xx series of high-speed ADCs from Intersil. These devices were widely used in defense and aerospace electronics during the era of ceramic packaging standards. The HSP43881JC-25 represents a specific speed grade within this family, offering a balance between conversion speed and power dissipation for fixed-function applications.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in verified sources. Cross-reference with other 25 MSPS, 8-bit ADCs from manufacturers such as Analog Devices or Texas Instruments, ensuring matching interface logic and package dimensions.
