HFA1113IBZ

Instrumentation, Op Amps, Buffer Amps Overview

The HFA1113IBZ is a high-speed buffer amplifier manufactured by Renesas Electronics in an 8-lead SOIC package. It features user-programmable output voltage limiting and closed-loop gains of +1, -1, or +2 without external resistors. The device operates within a temperature range of -40°C to 85°C with a typical supply voltage of ±5V. Key electrical specifications include an 850MHz bandwidth, a 2400V/µs slew rate, and a 13ns settling time. It provides low distortion (-73dBc at 30MHz) and sub-nanosecond overdrive recovery.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix (e.g., IBZ vs IBZ96) to confirm packaging type, as the datasheet lists standard tube and tape-and-reel options. Confirm RoHS compliance status if required for your manufacturing process. Ensure the selected variant matches the required operating temperature range of -40°C to 85°C. Check for any recommended replacement notices, as this component may be marked as not recommended for new designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the HFA1113IBZ when designing circuits requiring precise output voltage clamping to protect downstream components from saturation or damage. Choose this part for applications needing rapid overload recovery times and high linearity. Consider its internal gain flexibility to reduce bill-of-materials count compared to discrete resistor networks. Evaluate its suitability for driving capacitive loads like ADCs, keeping in mind the need for series output resistance to maintain stability.

Instrumentation, Op Amps, Buffer Amps Part Context

The HFA1113 belongs to the Intersil/Renesas HFA111x family of ultra-high-speed programmable gain buffer amplifiers. It shares architectural similarities with the HFA1112 but adds integrated output limiting capabilities. This family utilizes a proprietary complementary bipolar UHF-1 process to achieve high slew rates and wide bandwidths suitable for demanding video and RF signal processing tasks.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Public documentation indicates no recommended replacement parts are available for this component. Designers should verify current availability and lifecycle status directly with the manufacturer before finalizing procurement plans.
