Overview
The TSV992IYST is a dual operational amplifier from STMicroelectronics, part of the TSV99x and TSV99xA family. 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 wide bandwidth of 20 MHz and is stable for gains above 4 with a 100 pF capacitive load, while consuming only 1.1 mA maximum at 5 V. The TSV992IYST is ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.
