HFA1110IB

Instrumentation, Op Amps, Buffer Amps Overview

The HFA1110IB is a unity gain closed loop buffer manufactured on Intersil’s proprietary complementary bipolar UHF-1 process. It achieves a -3dB bandwidth of 750MHz, a slew rate of 1300V/µs, and a fast settling time of 7ns to 0.2%. The device provides high output current capability of 60mA and excellent video performance with low distortion. Operating within a temperature range of -40°C to +85°C, it is housed in an 8-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix (e.g., IB vs IBZ) to confirm lead-free compliance and RoHS status. Confirm that the component meets MIL-STD-883 requirements if military grade qualification is necessary, as standard versions may differ from the /883 variant. Ensure the datasheet revision matches the design requirements before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the HFA1110IB when a fixed unity gain buffer is required for high-frequency applications. Consider the HFA1112 if user-programmable gain options (+1, -1, +2) are needed without external components. Evaluate the HFA1113 if output clamping capabilities are required for overdrive protection. Ensure the PCB layout supports high-frequency operation with proper decoupling and ground planes.

Instrumentation, Op Amps, Buffer Amps Part Context

The HFA1110 is part of the HFA11xx series of ultra-high-speed buffer amplifiers designed for demanding signal processing tasks. Manufactured using the UHF-1 process, this family offers wide bandwidth and fast slew rates. The HFA1110 specifically serves as a pin-compatible upgrade for legacy parts like the AD9620 and CLC110, facilitating easier transitions to modern high-speed designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The datasheet explicitly recommends the HFA1112 as the replacement part for the HFA1110.
