LM139E/883

Quad comparator IC featuring low power consumption and low offset voltage. This surface mount device offers 4 independent comparator channels with a typical input offset voltage of 5mV and input bias current of 1nA. Operating across a wide temperature range from -55°C to 125°C, it supports dual supply voltages from ±2.5V to ±15V or single supply from 5V to 30V. Key performance metrics include a 60dB common mode rejection ratio and power supply rejection ratio, with a 16mA output current capability and a 5µs response time.
