The OPA1641AIDGKT: Its 11 MHz gain-bandwidth product and 20 V/µs slew rate deliver clean large-signal response well into the ultrasonic range, while the rail-to-rail output stage maximizes dynamic range in low-voltage single-supply designs. The FET input keeps input bias current at 2 pA, which matters when the source is a high-impedance microphone or piezo pickup. Supply current sits at 1.8 mA per channel, making it practical for multi-channel mixers or battery-powered recorders where every milliamp counts.
That span covers everything from a 5 V USB-powered audio interface to a ±15 V studio console. The 1.8 mA quiescent current is low enough that thermal buildup in a tightly packed 8-VSSOP footprint stays manageable, even with several devices on the same board.
It is not specified for under-hood or downhole temperatures, but for the vast majority of audio applications the industrial range is sufficient.
No exposed thermal pad to worry about — the 1.8 mA quiescent current keeps die temperature low even in still air.
