The MAX921CSA is a single, micro-power, low-voltage comparator designed for battery-powered and single-supply applications. It offers ultra-low supply current consumption of less than 4µA over its operating temperature range.
Key electrical features include an internal 1.182V ±1% bandgap voltage reference, adjustable hysteresis, and TTL/CMOS-compatible outputs capable of sinking and sourcing current. The comparator has a propagation delay of 12µs with a 10mV overdrive and a typical hysteresis of 50mV. It supports a wide power supply range, from a single +2.5V to +11V or a dual ±1.25V to ±5.5V.
This device is housed in an 8-SOIC package, suitable for surface mount applications. Its design minimizes parasitic feedback and eliminates power-supply glitches, making it easier to integrate into various electronic systems.
Applications for the MAX921CSA include battery-powered systems, threshold detectors, window comparators, and oscillator circuits.
