The single OPA180, dual OPA2180, and quad OPA4180 (OPAx180) operational amplifiers (op amps) use TI’s proprietary zero-drift techniques to simultaneously provide low offset voltage (75µV), and near zero-drift over time and temperature.These miniature, high-precision, low-quiescent-current op amps offer high input impedance and rail-to-rail output swing within 18mV of the rails. The input common-mode range includes the negative rail. These devices use single or dual supplies ranging from 4V to 36V (±2V to ±18V.

The dual-channel version is offered in VSSOP-8 packages and SOIC-8 packages. The quad-channel version is offered in SOIC-14 and TSSOP-14 packages. The single and quad package offerings (OPA180 and OPA4180) are specified from –40°C to +125°C, and the dual package (OPA2180) is specified from –40°C to +105°C.
