Product details

What this automotive-grade op-amp brings to the board

It delivers a 16 MHz gain-bandwidth product and a 27 V/µs slew rate, with rail-to-rail output swing. The part operates from a 4 V to 16 V supply span and draws 2.8 mA quiescent current. Input bias current is 10 pA, and input offset voltage is 4 mV. Output drive is rated at 74 mA per channel.

16 MHz GBW and 27 V/µs slew — what that buys you

The 16 MHz gain-bandwidth product and 27 V/µs slew rate suit fast sensor signals. The 2.8 mA supply current keeps thermal budget manageable.

Package and footprint — SOT-23-5

The single-channel layout simplifies routing on a mixed-signal board.

Frequently asked questions

Is TSX9291IYLT AEC-Q100 qualified for automotive applications?

Yes, the TSX9291IYLT is part of the Automotive, AEC-Q100 series, making it qualified for automotive-grade designs including under-hood and chassis-domain electronics.

What are the exact specifications of TSX9291IYLT including gain bandwidth and slew rate?

The TSX9291IYLT has a gain-bandwidth product of 16 MHz and a slew rate of 27 V/µs. It operates from 4 V to 16 V supply, draws 2.8 mA supply current, and delivers rail-to-rail output. Input bias current is 10 pA and input offset voltage is 4 mV. Output drive is 74 mA per channel.

Can TSX9291IYLT be used as a replacement for TSX9291ILT?

The TSX9291IYLT and TSX9291ILT share the same base part number but differ in packaging suffix. The 'Y' indicates tape-and-reel packaging; the 'I' indicates the temperature range. Verify the specific suffix against your BOM — the electrical specifications are identical.

Is TSX9291IYLT available via RFQ confirmation at major distributors like DigiKey or Mouser?

Stock availability at major distributors varies. The part is sourced and quoted to order through independent distribution — availability and current pricing are confirmed when you submit an RFQ.
