The ams-OSRAM USA INC. AS1973 is a dual, general-purpose voltage comparator featuring open-drain outputs. Designed for precision in signal conditioning and threshold detection, this component operates across a wide supply voltage range of 2.5V to 5.5V single or ±1.25V to ±2.75V dual. It offers a typical input bias current of 1pA at 5.5V and a low quiescent current of 32µA maximum. The device exhibits excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 80dB, alongside minimal input offset voltage of 6mV maximum and hysteresis of ±3mV. With a propagation delay of 400ns maximum, the AS1973 is suitable for applications in industrial automation, consumer electronics, and automotive systems requiring reliable voltage comparisons. The AS1973 is supplied in an 8-MSOP package, facilitating surface mounting.
