The LM139AD from Texas Instruments is a precision quad differential comparator, suitable for military-grade applications. This device features four independent voltage comparators designed to operate from a single power supply across a wide voltage range.
Key electrical specifications include a typical input offset voltage of 0.37mV and a low input bias current of 3.5nA. The comparator operates with a typical supply current of 200µA per comparator and offers a fast response time of 1µsec. The differential input voltage range can extend up to ±38V, equal to the maximum-rated supply voltage.
Packaged in a 14-SOIC (0.154", 3.90mm Width) surface-mount configuration, the LM139AD is rated for an operating temperature range of -55°C to 125°C. Its output is compatible with TTL, MOS, and CMOS logic levels, making it versatile for various circuit designs.
This comparator family is known for its common-mode input voltage range that includes ground and low output saturation voltage. The LM139AD is an obsolete part, with the LM139ADR identified as a potential replacement.
