LM2901D ST Comparator | 14-SO | Low Power, Wide Supply Range

Product Overview

The LM2901D is a low-power, low-offset voltage comparator from STMicroelectronics, designed for industrial and automotive applications. It features four independent comparators in a single 14-SO package, with a wide supply voltage range from 2V to 36V (single supply) or ±1V to ±18V (dual supply). The device offers low supply current (0.4 mA per comparator) and fast response time (1.3 μs typical). It is pin-compatible with standard LM2901 devices and operates over a temperature range of -40°C to +125°C.
