MAX931CUA-T Description

Short technical summary and product information.

The MAX931CUA-T is a single, micropower, low-voltage comparator designed for battery-powered systems and threshold detection applications. It offers ultra-low quiescent current, drawing a maximum of 4µA over the extended temperature range.

 

This comparator features an internal 1.182V ±2% bandgap voltage reference, providing stable reference voltage for comparisons. It operates from a single supply voltage of +2.5V to +11V or a dual supply of ±1.25V to ±5.5V. The input voltage range includes the negative supply rail. The MAX931CUA-T has TTL/CMOS-compatible outputs that can sink and source current up to 40mA.

 

With a propagation delay of 12µs (at 10mV overdrive), this device is suitable for applications requiring fast response times. It also includes programmable hysteresis for noise immunity and features an output stage that minimizes power-supply glitches. The device is available in a space-saving 8-uMAX package, making it ideal for designs with limited board space.

 

Key electrical characteristics include an input offset voltage of 10mV at 5V and typical CMRR/PSRR of 80dB. The operating temperature range is 0°C to 70°C.
