Opa1622 Dip8 Double Op Amp Finished Product Board High Current Output Low Distortion Op Amp Upgrade

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 OPA1622 supports a wide supply voltage range of 2V to 18V with a supply current of only 2.6m per channel. 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. colour:green Material:Metal + PC Package Contents: 1 * Amplifier board Only the above package content, other products are not included.
