The Texas Instruments OPA1602AIDR is a dual-channel audio operational amplifier from the SoundPlus™ series. It delivers a 35 MHz gain-bandwidth product and a 20 V/µs slew rate.
The 35 MHz gain-bandwidth product and 20 V/µs slew rate support audio bandwidth and fast transient response.
Yes, the OPA1602AIDR is a suitable replacement for the OPA2134 in most audio circuits. It offers higher bandwidth (35 MHz vs 8 MHz) and lower distortion, but both are dual op-amps in standard 8-pin DIP/SOIC footprints. Verify the compensation and supply voltage range — the OPA1602 operates from 4.5 V to 36 V, which covers the OPA2134's typical ±15 V rails.
The OPA1612 is a higher-performance dual audio op-amp with lower noise (1.1 nV/√Hz vs 2.5 nV/√Hz typical) and lower distortion, but it operates from a narrower supply range (4.5 V to 36 V same as OPA1602) and is typically more expensive. The OPA1602 offers a good balance of performance and cost for line-level audio stages where the ultimate noise floor is not required.
