Product details

The MAX923CSA+ from Maxim Integrated packs two comparators and a voltage reference into a single 8-SOIC. 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.

Frequently asked questions

Can MAX923CSA+ be used as a substitute for LM393 or LTC1440?

The MAX923CSA+ differs from the LM393 (no internal reference) and the LTC1440 (single comparator with reference). The MAX923CSA+ integrates two comparators plus a voltage reference, so it is not a direct pin-for-pin substitute for either. Check the pinout and reference voltage before substituting.
