Texas Instruments OPA1622 SoundPlus Audio Operational Amplifier Datasheet
The OPA1622 is a dual-channel, bipolar-input, SoundPlus™ audio operational amplifier designed for high-fidelity applications. It features ultra-low input voltage noise of 2.8 nV/√Hz at 1 kHz and an ultra-low total harmonic distortion plus noise (THD+N) of –119 dB when driving 32 Ω loads with 142 mW per channel.
The device supports a wide supply voltage range from ±2 V to ±18 V and offers high output drive capability, capable of delivering +145 mA/–130 mA. It includes a shutdown mode that reduces the quiescent current to less than 5 μA per channel to eliminate click-and-pop noise during power transitions. The OPA1622 is available in a small 10-pin VSON package. This manual is written in Chinese.
