HFA1212IP

Instrumentation, Op Amps, Buffer Amps Overview

The HFA1212IP is a dual, high-speed, low-power video closed-loop buffer manufactured by Intersil. It utilizes proprietary complementary bipolar UHF-1 technology to deliver high performance in a compact package. Key electrical characteristics include a typical supply current of 5.9mA per operational amplifier and a wide -3dB bandwidth of 340MHz. The device features a fast slew rate of 1155V/µs and excellent gain flatness up to 50MHz. It operates within an absolute maximum voltage range of 12V between V+ and V-, with short-circuit protected outputs capable of handling up to 60mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'IP' against official Intersil documentation to confirm package type and temperature range. Ensure compliance with MIL-STD-883 Class B screening if required for your application. Check for RoHS status as older Intersil parts may not be compliant. Confirm availability through authorized Renesas or Intersil distributors.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed video buffering is required with low power constraints. The dual configuration allows for cost-effective implementation in multi-channel systems. Consider the 340MHz bandwidth for signals requiring significant frequency response. Evaluate thermal dissipation capabilities given the CerDIP package's thermal resistance characteristics.
