That reference is the differentiator versus a plain dual comparator — you save one external reference IC and its associated bypass cap. The internal hysteresis is set at 50mV, which gives clean switching on slow-moving signals without external positive feedback resistors. Outputs are CMOS and TTL compatible, rated for 50mA sink/source, so they drive logic inputs or small loads directly. ## Speed and power — 12µs propagation delay, 7.5µA quiescent current Propagation delay is 12µs max. Quiescent current is 7.5µA max per comparator. ## Lifecycle — active production, no LTB risk The MAX923CSA+ carries an Active lifecycle status from the manufacturer and is ROHS3 compliant.","metaTitle":"MAX923CSA+ Comparator, Dual with Voltage Reference","metaDescription":"MAX923CSA+ dual comparator with integrated voltage reference.

The MAX923CSA+ integrates two comparators plus a voltage reference, so it is not a direct pin-for-pin substitute for either.
