Dual low-voltage comparator in SOIC-8
The STMicroelectronics LMV393ID is a dual general-purpose comparator in an 8-SOIC package.
Supply range and quiescent current
Supply range is 2.7V to 5.5V. Maximum quiescent current is 250µA.
Output drive and open-collector flexibility
Each output can sink 84mA at 5V. Outputs are open-collector.
Input offset and propagation delay
Maximum input offset voltage is 7mV at 5V. For a 100mV threshold, that is a 7% error — acceptable for overvoltage/undervoltage lockout or fan-speed control, but not for precision measurement. The 600ns propagation delay means this comparator is not intended for high-frequency switching; it suits DC or low-frequency threshold detection where loop response is in the microsecond range.
