Overview
The TSX921ILT is a single operational amplifier (op-amp) from the TSX92x family, manufactured by STMicroelectronics. This device is distinguished by its excellent AC characteristics, including a 10 MHz gain bandwidth, a 17 V/ms slew rate, and a low total harmonic distortion plus noise (THD+N) of 0.0003%. The TSX921ILT operates with a wide supply voltage range of 4 V to 16 V and features rail-to-rail input and output capabilities, making it versatile for various applications such as communications, I/V amplifiers for ADCs, and active filtering.
The device is available in the SOT23-5L package and is qualified for both industrial and automotive use, with a temperature range of -40 °C to 125 °C. It also includes a shutdown mode to reduce current consumption significantly when not in use.
