• Ultra-high speed performance with wide bandwidth and fast slew rates for signal integrity
• Low differential gain and phase distortion suitable for precision video applications

Instrumentation, Op Amps, Buffer Amps Applications

• Component and composite video systems
• High-speed data acquisition buffers
• Upgrade paths for low-gain amplifiers requiring higher closed-loop gain

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IPZ' against official Renesas documentation, as standard listings often cite 'HFA1112IP'. Confirm RoHS compliance status, as some variants are non-compliant. Check for end-of-life notifications or obsolescence notices prior to procurement. Ensure the supplier provides valid traceability for military-grade specifications if required.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed-gain buffer with flexible polarity options is needed without external feedback networks. Consider the 850 MHz bandwidth and 2400 V/µs slew rate for high-frequency signal conditioning. Evaluate the 8-PDIP package constraints for board space. Compare against the HFA1113 if output clamping functionality is required instead of programmable gain.

Instrumentation, Op Amps, Buffer Amps Part Context

The HFA1112 belongs to the Intersil/UHF-1 process family of ultra-high-speed amplifiers. It is designed to replace crystal oscillators or standard op-amps in high-frequency applications. The device offers flexibility by allowing gain configuration via pin selection, reducing inventory complexity compared to fixed-gain alternatives.
