Product details

22 MHz GBW — headroom for the audio band

Its 22 MHz gain-bandwidth product keeps the loop gain high well past 20 kHz, so distortion stays low across the audible band. The 17 V/µs slew rate handles fast transients like drum hits or digital audio glitches without slewing into distortion. Supply current is 1.5 mA per channel, which keeps the total quiescent draw at 3 mA for the dual — practical for multi-channel mixers or battery-powered recorders where every milliamp counts. Rail-to-rail output swing lets the part deliver maximum dynamic range into a following ADC or headphone driver without a separate rail booster.

Package and rework

The gull-wing leads are easy to inspect and reflow by hand or hot air — no hidden pads, no thermal pad to manage.

Frequently asked questions

How does OPA1662AID compare to OPA2134?

The OPA1662AID is a newer dual audio op-amp from the SoundPlus™ series with a 22 MHz GBW and 17 V/µs slew rate, compared to the OPA2134's 8 MHz GBW and 20 V/µs slew rate. The OPA1662AID offers wider bandwidth for higher-frequency signal chains while maintaining low distortion, and it operates from a wider supply range (3 V to 36 V vs. the OPA2134's 5 V to 36 V). Both are dual op-amps in SOIC-8 packages, but the OPA1662AID is the more modern choice for new designs.
