OPA1664: Sound Plus Low-Power, Low-Noise and Distortion, Audio Op Amps

The OPA1662 (dual) and OPA1664 (quad) series of bipolar-input operational amplifiers achieve a low 3.3 nV/√Hz noise density with an ultralow distortion of 0.00006% at 1 kHz. The OPA1662 and OPA1664 series of op amps offer rail-to-rail output swing to within 600 mV with 2-k(ohms) load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 mA.
