Single general-purpose voltage comparator includes ground

This post sponsored by Texas Instruments.

The LM397 from Texas Instruments is a single-voltage comparator with an input common mode that includes ground.  

The LM397 is designed to operate from a single 5V to 30V power supply or a split power supply. Its low 300µA supply current is virtually independent of the magnitude of the supply voltage. The LM397 features an open collector output stage. This allows the connection of an external resistor at the output. The output can directly interface with TTL, CMOS, and other logic levels by tying the resistor to different voltage levels (level translator).

The LM397 is available in space saving 5-Pin SOT-23 package and is pin compatible to TI’s TL331, single differential comparator. It has an industrial operating range of −40°C to +85°C and a response time of 440ns (50mV overdrive). The LM397 has a low input bias current of 7nA, a low input offset current of ±1n, and a low input offset voltage of ±2mV. Applications for the device range from A/D converters and peak detector to industrial uses.
