It comes in an 8-SOIC package (0.154\" width, 3.90 mm body) for surface-mount assembly. ## Latch function and noise rejection The latch holds the output state when asserted — useful for capturing a threshold crossing event in a data-acquisition or overcurrent-detection circuit where the input may oscillate around the trip point. Typical CMRR is 82.5 dB and PSRR is 80 dB, meaning common-mode and supply-rail noise are rejected well below the 4 mV maximum input offset — the comparator sees the signal, not the rail ripple. Maximum input bias current is 10 µA at ±5 V — high enough to matter with megohm-source impedances but acceptable for typical 10 kΩ divider or sensor interfaces. RoHS3 compliant.","metaTitle":"Analog Devices MAX903CSA+ Comparator with Latch, 8-SOIC","metaDescription":"MAX903CSA+ single comparator with latch, TTL output, 8-SOIC.
