Quad micropower op-amp for 3 V to 32 V rails
The gain-bandwidth product of 100 kHz and slew rate of 0.05 V/µs limit it to DC and low-frequency signals — think sensor buffering, level shifting, or set-point comparators, not audio or fast data acquisition.
The LP324M/NOPB operates from a single supply as low as 3 V up to 32 V, or split supplies of ±1.5 V to ±16 V. This covers common industrial rails — 5 V logic, 12 V sensor supplies, 24 V field loops — without an extra regulator.
For a 10 kΩ source impedance, 2 nA of bias contributes 20 µV of additional offset — negligible in most DC applications. The 10 mA per-channel output current can drive moderate loads like ADC inputs or logic gates, but not relays or solenoids directly.
