OPA180 - 0.1-μV/°C Drift, Low-Noise, Rail-to-Rail Output, 36-V, Zero-Drift Operational Amplifier

Updated : 2020-01-09 14:18:28
Description

The OPA180, OPA2180 and OPA4180 operational amplifiers (op amps) use TI’s proprietaryzero-drift techniques to simultaneously providelow 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 outputswing within 18 mV of the rails. The input common-mode range includes the negative rail. Single- ordual-supplies ranging from 4 V to 36 V (±2 V to ±18 V) can be used.

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