OPA2604 Advantage

OPA2604 Op Amp IC

The OPA2604 is a dual FET input operational amplifier designed for enhanced AC performance. Extremely low distortion, low noise and wide bandwidth provide excellent performance for high quality audio and other applications requiring excellent dynamic performance. New circuit technology and special laser trimming of dynamic circuit performance produce extremely low harmonic distortion. The result is an op-amp with excellent audio quality. the OPA2604's low-noise FET input provides a wide dynamic range, even at high source impedances. The offset voltage is laser-trimmed to minimize the need for interstage coupling capacitors. the OPA2604 is available in an 8-pin plastic mini-DIP and SO-8 surface mount package and is specified over a temperature range of -25°C to +85°C.

OPA2604 Circuit

Circuit schematics can help us better understand how a component or chip is used in a circuit and how it works. Making them work in an actual circuit is a reference.


OPA2604 Equivalent / Replacement

The equivalent of OPA2604 is OPA2134.

Before choosing an alternative, please understand the differences and compare the data sheet, pinout and application.
