What this dual op-amp does on the board
The LM2904DGKRG4: It delivers 700 kHz gain-bandwidth product and a 0.3V/µs slew rate — enough for sensor signal conditioning, active filtering below 100 kHz, and slow control loops, but not for high-speed ADC drivers or switching regulators.
Each channel draws 500 µA supply current and can source or sink 30 mA at the output. The 20 nA input bias current and 3 mV input offset voltage are typical for a general-purpose bipolar op-amp — adequate for non-inverting gain stages and comparator duty, but not precision instrumentation.
