MAX921CUA Description

Short technical summary and product information.

The MAX921CUA is a single comparator from Analog Devices Inc. designed for ultra-low power consumption, drawing less than 4µA of supply current. It includes an internal 1.182V ±1% bandgap voltage reference, making it suitable for battery-powered systems and threshold detection applications.

 

This comparator supports single supply operation from +2.5V to +11V or dual supply operation from ±1.25V to ±5.5V. It features programmable hysteresis, TTL/CMOS-compatible outputs, and a propagation delay of 12µs with a 10mV overdrive. The input voltage range includes the negative supply rail.

 

The MAX921CUA is available in an 8-pin uMAX/uSOP package and an 8-TSSOP, 8-MSOP package. It is designed for surface mount applications and operates within a temperature range of 0°C to 70°C.
