Audio channel op-amp in a compact SOT-23-5
Its 13 MHz gain-bandwidth product and 5 V/µs slew rate provide enough loop gain and slew margin for line-level audio up to the ultrasonic range, keeping distortion low in the audible band. Quiescent current sits at 940 µA per amplifier — low enough for multi-channel boards or battery-powered recorders without starving the power budget.
Input bias and offset — what they mean for audio
Input bias current is 10 pA (typical), and input offset voltage is 250 µV (max). For AC-coupled audio stages the bias current is negligible; the offset matters mainly in DC-coupled paths or when the amplifier drives a downstream ADC with a DC-restore loop. Neither parameter limits audio performance in the usual line-level or microphone preamp application.
Output drive and package
The SOT-23-5 (SC-74A) footprint is a standard five-pin package that fits tight channel spacing on a mixed-signal board.
