Analog Devices Inc./Maxim Integrated MAX921ESA is a single-channel comparator featuring an integrated voltage reference. This CMOS/TTL output device is housed in an 8-SOIC package and is designed for surface mount applications. It offers a typical power supply voltage range of 2.5V to 11V for single supply and ±1.25V to ±5.5V for dual supplies. Key specifications include a maximum input offset voltage of 10mV at 5V, 50mV hysteresis, and a propagation delay of 12µs. The component exhibits excellent common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) of 80dB. Quiescent current is a low 5µA, with a typical output current of 50mA. This comparator finds application in industrial, automotive, and consumer electronics where precise voltage comparison and reference generation are critical.
