STMicroelectronics TSV631 and TSV631A

The TSV631 and TSV631A devices are single operational amplifiers offering low voltage, low power operation, and rail-to-rail input and output. These devices have a very low input bias current and a low offset voltage making them ideal for applications that require precision. They can operate at power supplies ranging from 1.5 V to 5.5 V, and are therefore very suitable for battery powered devices, extending battery life. These op-amps feature an excellent speed/power consumption ratio, offering an 880 kHz gain bandwidth while consuming only 60 µA at a 5 V supply voltage. They are unity gain stable for capacitive loads up to 100 pF. The devices are internally adjusted to provide very narrow dispersion of AC and DC parameters. All devices are offered in micropackages and are guaranteed for industrial temperature ranges from -40° C to 125° C. These features combined make the TSV631 and TSV631A ideal for sensor interfaces, battery supplied and portable applications, as well as active filtering.

Available tools

STEVAL-CCA022V1:

Demonstration board for single op-amps in SC70 or SOT-23 packages

The STEVAL-CCA022V1 demonstration board is designed to help characterize single operational amplifiers in SOT23-5 (two different pinouts) and SC70-5 packages. Operational amplifiers in SOT23-6 and SC70-6 packages can also be characterized but their standby pin is not usable because it is connected to VCC + on the board.
