Dual comparator with Beyond-the-Rails™ input range
The MAX962ESA+T from Maxim Integrated is a dual general-purpose comparator in an 8-SOIC package. It operates from a single 2.7V to 5.5V supply or dual supplies, and its Beyond-the-Rails™ series input stage handles signals that swing beyond the supply rails — useful for level translation and zero-crossing detectors in mixed-voltage systems. Outputs are CMOS and TTL compatible, so it drives logic inputs directly without a pull-up resistor on the output side. Built-in 3.5 mV hysteresis cleans up noisy edges without external feedback components, and the 7 ns max propagation delay keeps it fast enough for high-frequency signal conditioning, pulse-width measurement, and over-current detection loops.
7 ns propagation delay — what it means for the loop
At 7 ns max, the comparator's response keeps phase lag low in a feedback path. The 9 mA quiescent current per channel is the trade-off for that speed.
