High-performance op-amp achieves low 2.8nV/vHz noise density and more

This post is sponsored by Texas Instruments. The Texas Instruments (TI) OPA1622, dual, bipolar-input, SoundPlus audio operational amplifier achieves a very low, 2.8nV/vHz noise density with an ultra-low THD+N of -119.2dB at 1kHz, while driving a 32ohm load at 100mW output power. The OPA1622 offers extremely-high ac PSRR and CMRR specifications that eliminate noise from power supplies, making it ideal for use in portable-audio applications. The device also has a high output-drive capability of +145mA / -130mA.
