The OP220 is a monolithic dual operational amplifier that can
be used either in single or dual supply operation. The low offset
voltage and input offset voltage tracking as low as 1.0
mV/鈭濩,
make this the first micropower precision dual operational amplifier.
The excellent specifications of the individual amplifiers com-
bined with the tight matching and temperature tracking between
channels provides high performance in instrumentation ampli-
fier designs. The individual amplifiers feature extremely low
input offset voltage, low offset voltage drift, low noise voltage,
and low bias current. They are fully compensated and protected.
Matching between channels is provided on all critical parameters
including input offset voltage, tracking of offset voltage versus
temperature, noninverting bias currents, and common-mode
rejection ratios.
