OPA2604 (dual op amp) and OPA604 (single op amp) are products of Burr-Brown (referred to as BB Company) in the United States. They are op amps specially designed for audio. Known as the op amp with tube tone. The price was not low back then, but it was still upgraded as a motorcycle by many audiophiles.

The OPA2604AP is a dual FET input high performance audio operational amplifier. It has low distortion, low noise, high signal-to-noise ratio, and high bandwidth, and is widely used in high-quality audio circuits and other circuits that require dynamic performance. The low-noise FET input circuit of the OPA2604AP provides a large dynamic range and extremely small offset voltage. The operating voltage range can be from ±4.5V to ±24.0V, the distortion is only 0.0003 at 1KHz, the slew rate is 25V/μs, and the gain bandwidth is 20MHz.

It can directly replace the low-end op amps such as NE5532 JRC4558/4580 OP275 LT1057, and the effect is good! This batch of Korean-made OPA2604AP in our shop is packaged by an old Korean manufacturer of BB Company, and ordered at a high price. The enthusiasts responded enthusiastically and received rave reviews~!
