Channel | The OPA1622 is a dual bipolar input SoundPlus audio operational amplifier The device features a low noise density of 2 8nV Hz and a low N of 119 2dB at 1kHz while also driving a 32ohm load at 100mW output |
---|---|
Power | The OPA1622 s high AC Power Supply Rejection Ratio PSRR and Common Mode Rejection Ratio CMRR specifications eliminate noise from the power supply and are perfect for portable audio applications In addition the device features a high output drive of 145mA 130mA for direct drive |
Headphone | The output current of the general operational amplifier NE5532 OPA2604 is less than 50MA and the output of OPA1622 is up to 145MA which greatly increases the driving force so that the circuit has better matching lower output impedance high and low level dynamic and therefore very good performance |
