The dual OPA1662 and quad OPA1664 (OPA166x) series of bipolar-input SoundPlus™ audio operational amplifiers achieve a low 3.3nV/√Hz noise density with an ultra-low distortion of 0.00006% at 1kHz. The OPA166x series of op amps offer rail-to-rail output swing to within 600mV with 2kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30mA.
These devices operate over a very wide supply range of ±1.5V to ±18V, or 3V to 36V, on only 1.5mA of supply current per channel. The OPA166x op amps are unity-gain stable and provide excellent dynamic behavior over a wide range of load conditions.
These devices also feature completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.
The OPA166x are specified from –40°C to +85°C.
