OPA2180 Zero-Drift Operational Amplifiers


TI's low-noise, rail-to-rail output, 36 V, 0.1 µV/°C drift op amp

TI's OPA2180 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 to 36 V (±2 to ±18 V).
