OPA1602AID

OPA1602AID Description

The OPA1602AID from Texas Instruments is a high-performance, dual-channel audio operational amplifier (op-amp) belonging to the SoundPlus™ series. Designed for precision audio applications, it operates over a 4.5V to 36V supply range, making it versatile for both portable and high-voltage systems. With a Gain Bandwidth Product (GBW) of 35 MHz and a slew rate of 20V/µs, it delivers exceptional signal fidelity and transient response, ideal for high-fidelity audio processing. The device features ultra-low input bias current (20 nA) and low input offset voltage (100 µV), ensuring minimal distortion and accurate signal reproduction. Packaged in an 8-SOIC tube, it is RoHS3 compliant and suitable for surface-mount applications.
