Dual comparator with an onboard reference — what it means for the BOM
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.
Lifecycle — active production, no LTB risk
The MAX923CSA+ carries an Active lifecycle status from the manufacturer and is ROHS3 compliant.
