Overview
The TSV992AIST, part of the TSV99x and TSV99xA family, is a single operational amplifier produced by STMicroelectronics. This device is characterized by its low voltage operation, rail-to-rail input and output, and an excellent speed/power consumption ratio. It offers a 20 MHz gain-bandwidth product, making it stable for gains above 4 with a 100 pF capacitive load, while consuming only 1.1 mA maximum at 5 V. The TSV992AIST is ideal for applications requiring low power consumption, high speed, and precision, such as sensor interfaces, battery-supplied devices, portable applications, and active filtering.
