OPA180QDGKRQ1 General Description

The OPA180-Q1 and OPA2180-Q1 operational amplifiers (op amps) use TIs proprietary 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 op amps 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. Single- or dual-supplies ranging from 4 V to 36 V (±2 V to ±18 V) can be used.

The single-channel and dual-channel versions are offered in VSSOP-8 packages. The single package offering (OPA180-Q1) is specified from –40°C to +125°C, and the dual package (OPA2180-Q1) is specified from –40°C to +105°C.
