Dual op-amp in SOT-23-8 — board-fit and signal chain
The MAX4494AKA+T: The 3V/µs slew rate sets the large-signal bandwidth ceiling — for a 2 Vpp output swing, the full-power bandwidth is roughly 240 kHz, which is adequate for sensor conditioning, ADC drivers, and active filters in the audio and low-frequency instrumentation range. Each channel draws 770 µA supply current, keeping the total quiescent draw under 1.6 mA for the dual — this fits battery-powered or loop-powered designs where every milliamp matters.
