Overview
The TSV911AILT operational amplifier from STMicroelectronics is part of the TSV91x and TSV91xA series, offering low voltage operation with rail-to-rail input and output. This op-amp is characterized by its excellent speed/power consumption ratio, providing an 8 MHz gain-bandwidth product while consuming only 1.1 mA maximum at 5 V. It is unity gain stable and features an ultra-low input bias current, making it ideal for sensor interfaces, battery-supplied and portable applications, as well as active filtering.
