Texas Instruments OPA1664
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.| Part No. | OPA1664 |

DESCRIPTION
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 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.
