Dual comparator with 80 ns propagation delay
The MAX942CSA+T is a dual general-purpose comparator from Analog Devices, integrating two independent comparators in a single 8-SOIC package. The output stage supports CMOS, push-pull, and TTL logic families, so it interfaces directly with downstream logic without needing a pull-up resistor on the output.
The dual-supply capability (e.g., ±2.5 V) suits bipolar analog front-ends where the input common-mode range must include ground. Typical CMRR and PSRR of 81.94 dB each ensure the comparator rejects common-mode noise and supply ripple — important when the reference threshold is a fraction of the supply rail.
