The TSV6290 comes with a shutdown function.
The TSV6290 and TSV6291 present a high
tolerance to ESD, sustaining 4 kV for the human
body model.
Additionally, the TSV6290 and TSV6291 are
offered in SC70-5/6 and SOT23-5/6
micropackages, with extended temperature
ranges from -40° C to +125° C.
All these features make the TSV629x ideal for
sensor interfaces, battery-supplied and portable
applications, as well as active filtering.
With a very low input bias current and low offset
voltage (800 µV maximum for the A version), the
TSV629x family of devices is ideal for applications
requiring precision. The devices can operate at a
power supply ranging from 1.5 to 5.5 V, and
therefore suit battery-powered devices, extending
battery life.
