OPA1622 SoundPlus Audio Operational Amplifier

Texas Instruments OPA1622 SoundPlus™ Audio Operational Amplifier is a dual, bipolar-input audio operational amplifier that achieves a very low, 2.8nV/√Hz noise density. This is done with an ultra-low THD+N of -119.2dB at 1kHz while driving a 32Ω load at 100mW output power. The OPA1622 offers extremely high AC PSRR and CMRR specifications that eliminate noise from power supplies which makes the OPA1622 ideal for use in portable audio applications. This device also has a high output drive capability of +145mA / -130mA. The OPA1622 operates over a very wide supply range of ±2V to ±18V, on only 2.6mA of supply current per channel. The OPA1622 op-amp is unity-gain stable and provides excellent dynamic behavior over a wide range of load conditions.
