Audio amp said to have lowest distortion, noise

The OPA1622 is said to set the latest standard in audio performance with total harmonic distortion of -116 dB at 10 mW output into a 32 Ω load. The two channel amp delivers up to 150 mW out, requires only 2.6 mA quiescent current/channel, typical, and comes in a small 3 x 3 mm VSON10 package.

The amplifiers noise density is a very low 2.8 nv/√Hz at 1 kHz and it features a 32 MHz (at G = 1,000) gain-bandwidth product. It has a shutdown mode taking only 5 µA/channel. Supply range is ±2 to ±18 V, PSRR is 0.1 µV/V, typical, and CMRR 127 db typical. Available now at $2.90 ea/1,000
