The OPA1622 is a dual-channel, bipolar input, SoundPlus audio operational amplifier. The device has a low noise density of 2.8nV/√Hz and a low THD+N of -119.2dB at 1kHz, while being able to drive a 32Ω load at 100mW output power. The OPA1622 has high AC power supply rejection ratio (PSRR) and common-mode rejection ratio (CMRR) specifications to eliminate noise from the power supply, making it ideal for portable audio applications. In addition, the device has a high output drive capability of +145mA/-130mA to directly drive headphones. OPA1622 supports a wide power supply voltage range of ±2V to ±18V, and the power supply current per channel is only 2.6m General op amps such as NE5532 and OPA2604 have an output current of less than 50MA, while OPA1622 outputs up to 145MA, which greatly increases the driving force, making the circuit more compatible, with lower output impedance, high and low bass levels, and very good dynamic performance.
