OPA1604AIDR

OPA1604AIDR Description

The OPA1604AIDR from Texas Instruments is a high-performance, quad-channel audio operational amplifier from the SoundPlus™ series, designed for precision audio applications. Packaged in a 14-SOIC surface-mount configuration and supplied in tape & reel (TR), this IC delivers exceptional signal fidelity with ultra-low noise and distortion. Operating over a 4.5V to 36V supply range, it supports a 35 MHz gain bandwidth product (GBW) and a 20V/µs slew rate, ensuring high-speed signal processing. With 100 µV input offset voltage and 20 nA input bias current, it maintains accuracy in sensitive audio circuits. The ROHS3-compliant device is ideal for professional audio equipment, offering 30 mA output current per channel and 2.6mA supply current per amplifier (x4 channels) for efficient power management.
