TSX9291ILT

Instrumentation, Op Amps, Buffer Amps Overview

The TSX9291ILT is a single-channel, rail-to-rail input and output CMOS operational amplifier manufactured by STMicroelectronics. It features a gain bandwidth product of 16 MHz and a slew rate of 27 V/µs at a supply voltage of 16 V. The device operates within a wide supply voltage range of 4 V to 16 V and consumes a typical operating current of 2.8 mA. Key electrical parameters include an input bias current of 10 pA, an input offset voltage of 5 mV, and an input voltage noise density of 17.9 nV/√Hz. It provides an output current capability of 82 mA per channel and maintains stability in gain configurations higher than 2 or lower than -1.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (-40°C to +125°C) and 'LT' denotes the SOT-23-5 tape and reel packaging configuration. Confirm that the component meets AEC-Q100 automotive reliability requirements if intended for automotive use. Ensure the design accounts for decompensated stability, requiring a minimum closed-loop gain magnitude greater than 2 or less than -1.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high-speed signal processing is required alongside low power consumption in a compact package. It is suitable for designs needing rail-to-rail swing across a wide 4 V to 16 V supply range. Consider its decompensated nature for stability; it is not unity-gain stable. Compare against the TSX92 series if unity-gain stability is a mandatory requirement for the application topology.

Instrumentation, Op Amps, Buffer Amps Part Context

The TSX9291 belongs to the TSX92 series of 16 V CMOS operational amplifiers from STMicroelectronics. This series is designed for applications demanding excellent AC characteristics and low power efficiency. Unlike the TSX92 series which offers unity-gain stability, the TSX929x variants are decompensated to achieve superior speed and bandwidth performance while maintaining low current consumption.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

For unity-gain stable alternatives within the same family, consider the TSX921. For lower voltage operation, the TSV9 series may be appropriate. For micro-power requirements, the TSX6 series offers lower current consumption at the expense of bandwidth.
