Product details

Package and supply integration

The TSV991ILT comes in a SOT-23-5 (SC-74A) package, surface-mount, with a 5-pin footprint that fits tight board layouts where single-channel op amps are needed. Supply span runs from 2.5 V to 5.5 V, so it operates on a single 3.3 V or 5 V rail without a split supply — common in battery-powered and portable equipment.

Speed and precision for signal conditioning

With 20 MHz gain-bandwidth product and a 10 V/µs slew rate, this op amp handles fast sensor signals and ADC driver stages where settling time matters. Input bias current is 1 pA typical — negligible for high-impedance sources like photodiodes or pH probes, where bias current error would otherwise dominate the offset. Rail-to-rail output swing means the output can reach within millivolts of the supply rails, preserving dynamic range in low-voltage single-supply chains.

Temperature range and supply current

Rated for -40°C to 125°C, the TSV991ILT is suited for industrial enclosures, automotive cabin environments, and outdoor equipment where ambient temperature swings are wide. Quiescent supply current is 820 µA per amplifier — a reasonable draw for a 20 MHz device, balancing speed against battery life in portable designs.

Frequently asked questions

What is the closest functional second-source for TSV991ILT?

The TSV992 family (e.g., TSV992AIYST, TSV992AIDT, TSV992IQ2T) shares the same 20 MHz GBW, 10 V/µs slew rate, 1 pA input bias, and rail-to-rail output, but is a dual-channel (2-circuit) device in a different package. The TSV991ILT is a single-channel part; the dual version doubles the channel count per package and requires a different PCB footprint.

What compliance documentation does STMicroelectronics provide for TSV991ILT?

The TSV991ILT is RoHS3 compliant (2011/65/EU). Standard STMicroelectronics material declarations and conflict minerals reports are available through their documentation portal.
