The LM139ADR from Texas Instruments is a precision quad differential comparator designed for robust performance. It features four independent comparators within a single package, making it efficient for space-constrained designs.
Key electrical specifications include a low input offset voltage of 0.37mV and a low input bias current of 3.5nA. The device operates with a differential input voltage range up to ±38V and a low supply current of 200µA per comparator. Its output is compatible with TTL, MOS, and CMOS logic levels.
This comparator is housed in a 14-SOIC package and is designed for surface mounting. It operates reliably within an extended temperature range of -55°C to 125°C, making it suitable for demanding environmental conditions. The LM139ADR is an obsolete part, with newer 'B' versions offering improved specifications and acting as drop-in replacements.
Applications for this comparator include voltage sensing, threshold detection, and signal conditioning in various electronic systems.
