The Texas Instruments LM239ADR is a quad differential comparator integrated circuit designed for versatile operation. It can function with single power supplies ranging from 2V to 36V or dual supplies from ±1V to ±18V. Each of the four independent comparators offers an open-collector output, compatible with TTL, MOS, and CMOS logic levels, enabling wired-AND logic configurations.
Key electrical characteristics include a typical supply current of 0.8 mA, low input bias current of 25 nA, and low input offset voltage of 2 mV. The common-mode input voltage range includes ground, and the differential input voltage range can extend up to the maximum-rated supply voltage of ±36V. The device has a typical propagation delay of 1.3 µs.
This comparator is housed in a 14-SOIC package, suitable for surface mounting. The operating temperature range is -25°C to 85°C. Its design makes it suitable for various signal comparison and threshold detection applications in electronic circuits.
