The ams-OSRAM USA INC. AS1977-T is a single-element, general-purpose CMOS comparator featuring an open-drain, rail-to-rail output. Designed for surface mount applications, it is supplied in a SOT-23-5 package on tape and reel. This component offers a low input bias current of 0.001µA at 5V and a quiescent current of 500nA maximum. Key electrical specifications include a typical CMRR of 74dB and PSRR of 86.02dB, with a maximum input offset voltage of 5mV at 5V and 3mV hysteresis. The output can sink up to 50mA. Operating over a temperature range of -40°C to 85°C, the AS1977-T is suitable for single supply voltages from 1.8V to 5.5V. Its propagation delay is a maximum of 18µs. This device finds application in various electronic systems, including industrial control and consumer electronics.
