) shifts the output voltage (V
OUT
).
The supply voltage range (1.8V to 5.5V) is low enough
to support many portable applications. All devices are
fully specified from -40°C to +125°C.
These parts have five minimum gain options (1, 2, 5, 10
and 100 V/V). This allows the user to optimize the input
offset voltage and input noise for different applications.
