The LM2902PWRG4: Total quiescent current is 1.4 mA across all four channels.
These are standard figures for a general-purpose bipolar op-amp — adequate for DC-accurate signal chains like thermocouple amplifiers or current-sense circuits where the signal is in the tens of millivolts, but not for precision microvolt-level measurements.
For heavier loads, an external transistor stage is needed.
The slew rate is 0.5 V/µs. For a 1 V peak-to-peak output swing, the full-power bandwidth is about 80 kHz — above that, the output will distort. This part is fine for audio, sensor filtering, and slow control loops, but not for high-speed video or fast data acquisition.
