FHP3131IS6X

Instrumentation, Op Amps, Buffer Amps Overview

The FHP3131IS6X is a high-performance voltage-feedback operational amplifier manufactured by onsemi, formerly Fairchild Semiconductor. It operates within a supply voltage range of 2.5V to 12V and consumes only 0.4mA of typical supply current. The device provides a unity-gain bandwidth of 70MHz and a slew rate of 50V/μs at +5V. It features rail-to-rail output capability and an input common-mode voltage range that extends below the negative rail. A dedicated disable pin allows for power-down operation with current consumption dropping below 30μA. The component is housed in a space-saving SOT23-6 package and is rated for an operating temperature range from -40°C to +85°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix IS6X corresponds to the SOT23-6 package variant when sourcing. Confirm the manufacturer lineage as the product originated from Fairchild Semiconductor before its acquisition by onsemi. Ensure the procurement channel provides documentation reflecting the correct datasheet revision to guarantee accurate electrical parameter compliance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low quiescent current alongside high-speed signal fidelity. The rail-to-rail input and output characteristics make it suitable for single-supply systems where maximizing dynamic range is critical. Consider the thermal resistance of the SOT23-6 package when designing for high ambient temperatures or heavy load conditions.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the FHP3131 series of high-speed amplifiers. The IS6X designation specifically identifies the SOT23-6 surface-mount package configuration. The IL6X variant utilizes the MicroPak-6 package. Both variants share identical electrical specifications and are designed for general-purpose high-speed applications requiring minimal power consumption.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional replacements include the FHP3131IL6X which utilizes the MicroPak-6 package instead of SOT23-6. Designers should verify pinout compatibility and package dimensions when substituting between these two form factors.
