FHP3132IS5X

Instrumentation, Op Amps, Buffer Amps Overview

The FHP3132IS5X is a single-channel, high-speed voltage feedback operational amplifier manufactured by onsemi (formerly Fairchild Semiconductor). It operates within a supply voltage range of 2.7V to 12V and consumes 2.5mA of supply current per amplifier. The device features a gain-bandwidth product of 260MHz at ±5V supplies and a slew rate of 400V/μs. It provides rail-to-rail output performance with an input common-mode voltage range that includes the negative rail. The component is housed in a lead-free SOT23-5 package and is rated for operation from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the manufacturer origin, as the component was originally produced by Fairchild Semiconductor before its acquisition by onsemi. Confirm the specific ordering suffix IS5X corresponds to the SOT23-5 package and reel packaging method. Ensure the operating temperature range meets the application requirements of -40°C to +85°C. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this amplifier for applications requiring high bandwidth and low power consumption in a compact footprint. The rail-to-rail input and output characteristics make it suitable for single-supply or dual-supply systems where signal swing maximization is critical. Consider the 2.5mA quiescent current when designing battery-powered portable devices. Ensure the load impedance allows for the specified linear output current of ±100mA without exceeding thermal limits.
