HFA1100IJ

Instrumentation, Op Amps, Buffer Amps Overview

The HFA1100IJ is a high-speed, wideband current feedback operational amplifier manufactured by Harris Corporation. It features a -3dB bandwidth of 850 MHz and a slew rate of 2300V/µs. The device operates on supply voltages ranging from 4.5V to 11V, with a typical supply current of 21mA. Key electrical parameters include an input offset voltage of 2mV, an input bias current of 25µA, and an output current capability of 60mA per channel. It is housed in an 8-SOIC surface-mount package and supports an operating temperature range of -40°C to 85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IJ' against official manufacturer documentation to confirm the exact package type and material composition. Ensure compatibility with RoHS regulations if required by your application, as older Harris products may not meet current environmental standards. Confirm availability status directly with authorized distributors or manufacturers like Renesas Electronics, which currently produces this family.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the HFA1100IJ when high slew rate and wide bandwidth are critical requirements for video or RF applications. Compare its current feedback topology against voltage feedback alternatives to ensure stability with capacitive loads. Verify that the 8-SOIC package fits your PCB layout constraints and thermal management strategy. Consider the 2mV input offset voltage for precision requirements in your specific signal chain design.

Instrumentation, Op Amps, Buffer Amps Part Context

The HFA1100 series represents a line of high-performance current feedback amplifiers designed for demanding analog signal processing tasks. Originally developed by Harris Semiconductor, the product line has been maintained and distributed by subsequent owners such as Intersil and Renesas Electronics. This series is characterized by its ability to handle fast-changing signals with minimal distortion, making it a staple in professional video and communications hardware.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The HFA1100IBZ is a verified alternative within the same family, offering identical electrical specifications but packaged in an 8-SOIC format instead of the DIP variant. Check datasheets for pinout compatibility before substitution.
