3 Description
The OPA180, 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 VSSOP-8 and SOIC-8
packages. The quad is offered in SOIC-14 and
TSSOP-14 packages. All versions are specified for
operation from –40°C to 105°C.
