HI1-0305/883

Overview

The HI1-0305/883 is a high-speed operational amplifier manufactured by Harris Corporation, designed for demanding signal processing applications. This device integrates four independent circuits within a single package, offering robust performance across a wide temperature range of -55°C to 125°C. It features a gain-bandwidth product of 40 MHz and a slew rate of 25 V/µs, ensuring rapid response to input changes. The amplifier operates on supply voltages ranging from ±5 V to ±18 V, with an input offset voltage typically around 2 mV. Packaged in a 20-pin ceramic leaded chip carrier (CLCC), it supports surface-mount installation and draws a supply current of approximately 16 mA per circuit.

Feature Summary

• High-speed operation with 40 MHz gain-bandwidth product and 25 V/µs slew rate
• Wide operating temperature range suitable for harsh environments
• Quad configuration providing four independent amplifiers in one package
• Low input offset voltage for precision signal conditioning

Applications

• Video signal processing and buffering
• High-frequency data acquisition systems
• Instrumentation requiring fast transient response
• Military and aerospace electronic systems

Procurement Notes

Verify the specific suffix designation against official Harris or Intersil datasheets to confirm pinout compatibility and electrical tolerances. Ensure that the procurement source provides traceability documentation, as this component may be classified under export control regulations. Confirm RoHS compliance status if required for modern assembly processes, noting that older variants may not meet current environmental standards.

Selection Notes

Select this component when system requirements demand high bandwidth and fast settling times compared to standard general-purpose amplifiers. Consider the thermal management capabilities of the CLCC package for high-temperature operations up to 125°C. Evaluate power supply constraints, as the device requires dual supplies within the ±5 V to ±18 V range to function correctly within its specified linear region.

Part Context

This part belongs to the HI-1 series of high-speed operational amplifiers produced by Harris Corporation, later continuing through Intersil and Renesas. These devices were widely used in professional video and communication equipment before being superseded by newer CMOS-based architectures. The /883 suffix indicates a military-grade qualification level, ensuring stricter manufacturing controls and reliability standards compared to commercial variants.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided reference material. Users should consult official manufacturer cross-reference guides for compatible alternatives such as the HA-2515 or similar quad high-speed op-amps, verifying pin compatibility and electrical specifications before substitution.
