With 1 pA input bias current and 1.5 mV input offset voltage, the TSV991AIQ2T handles high-impedance sensors without loading the source.
If you need a dual-channel variant for a tighter BOM, the TSV912IDT is a pin-compatible second source in the same family — same supply range, same temperature grade, but two amplifiers per package and a lower 8 MHz GBP.
The gain-bandwidth product is 20 MHz. That means at a closed-loop gain of 10, you get a usable bandwidth of about 2 MHz — enough for audio processing, sensor filtering, and moderate-speed ADC drivers.
With a 20 MHz GBP and 10 V/µs slew rate, it has enough bandwidth for line-level audio up to 20 kHz. The 1.5 mV offset and 820 µA quiescent current are typical for a general-purpose op-amp — it will work for non-critical audio paths (headphone drivers, active filters), but for low-noise or high-fidelity stages you would want a dedicated audio op-amp with lower noise density.
It comes in an 8-UFDFN with exposed pad (supplier package 8-DFN, 2x2 mm body). The exposed pad must be soldered to a thermal land on the PCB for heat dissipation.
