Overview
The TSV634AIPT is a part of the TSV63x and TSV63xA series of operational amplifiers produced by STMicroelectronics. This family of dual and quad operational amplifiers is designed for low-voltage operation and features rail-to-rail input and output. The TSV634AIPT is particularly suited for applications requiring low power consumption and high performance in a compact package.
The device offers an excellent speed/power consumption ratio, with a gain-bandwidth product of 880 kHz while consuming only 60 µA at a 5 V supply voltage. It also features an ultralow input bias current and includes a shutdown mode, making it ideal for battery-powered, portable, and sensor interface applications.
