DESCRIPTION
The OPA2180 and OPA4180 operational amplifiers
use zero-drift techniques to simultaneously provide
low offset voltage (75 μV), and near zero-drift over
time and temperature. These miniature,
high-precision, low quiescent current amplifiers offer
high input impedance and rail-to-rail output swing
within 18 mV of the rails. The input common-mode
range includes the negative rail. Either single or dual
supplies can be used in the range of +4.0 V to +36 V
(±2 V to ±18 V).
The dual version is offered in MSOP-8 and SO-8
packages. The quad is offered in SO-14 and
TSSOP-14 packages. All versions are specified for
operation from –40°C to +105°C.
