Sound Plus Low-Power, Low-Noise and Distortion, Audio Op Amps - OPA1662

OPA1662 (ACTIVE)

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

 

Description

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-kΩ load, which increases headroom and maximizes dynamic range. These devices also have a high output drive capability of ±30 mA.

These devices operate over a very wide supply range of ±1.5 V to ±18 V, or +3 V to +36 V, on only 1.5 mA of supply current per channel. The OPA1662 and OPA1664 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 OPA1662 and OPA1664 are specified from –40°C to +85°C.
