The OPA169x operational amplifiers achieve a new level of performance for low-power amplifiers with a low 4.2-nV/√Hz noise density and distortion of –127 dB at 1 kHz. This op amps offer rail-to-rail output swing to within 200 mV of the power supplies with a 2-kΩ load, which increases headroom and maximizes dynamic range. These devices have a high output drive capability of ±50 mA.
The OPA169x operational amplifiers operate over a wide supply range of ±1.75 V to ±18 V, or 3.5 V to 36 V (on 650 µA of supply current per channel), are unity-gain stable, and provide excellent dynamic behavior over a wide range of load conditions.
The OPA169x op amps are specified for a temperature range of –40°C to 125°C.
