LM239PT Description

Short technical summary and product information.

The LM239PT from STMicroelectronics is a precision voltage comparator designed for versatile operation from a single power supply over a wide voltage range, or from split power supplies. Its input common-mode voltage range includes ground, even when operated from a single supply. The device features a very low supply current that is independent of the supply voltage, making it suitable for power-sensitive applications.

 

Key electrical characteristics include a low input bias current of 25 nA typical, a low input offset current of ±5 nA typical, and a low input offset voltage of ±1 mV typical. The output saturation voltage is 250 mV typical at 4 mA sink current. The differential input voltage range is equal to the supply voltage. Outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families.

 

This comparator operates over a temperature range of -25°C to 125°C. It is available in a 14-TSSOP surface mount package, supplied on tape and reel. The LM239PT is characterized for operation from –25°C to 125°C.
