Description
The TSV630 and TSV631 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. The TSV630 provides a shutdown
function. All devices are offered in
micropackages and are guaranteed for industrial
temperature ranges from -40 ° C to 125 ° C.
These features combined make the TSV630 and
TSV631 ideal for sensor interfaces, battery-
supplied and portable applications, as well as
active filtering.
