The TSV621 is a single operational amplifier
offering low voltage, low power operation and rail-
to-rail input and output.
With a very low input bias current and low offset
voltage (800 µV maximum for the A version), the
TSV621 is ideal for applications that require
precision. The device can operate at a power
supply ranging from 1.5 to 5.5 V, and therefore
suits battery-powered devices and extends
This product features an excellent speed/power
consumption ratio, offering a 420 kHz gain
bandwidth while consuming only 29 µA at a 5-V
This operational amplifier is unity gain stable for
capacitive loads up to 100 pF.
The device is internally adjusted to provide very
narrow dispersion of AC and DC parameters,
especially power consumption, product gain
bandwidth and slew rate.
The TSV621 presents a high tolerance to ESD,
sustaining 4 kV for the human body model.
Additionally, the TSV621 is offered in SC70-5 and
SOT23-5 micropackages, with extended
temperature ranges from -40° C to +125° C.
All these features make the TSV621 ideal for
sensor interfaces, battery-supplied and portable
applications, as well as active filtering.
