The dual-supply option (±1.25 V to ±2.75 V) allows direct interfacing with bipolar analog front-ends without level shifting. ## Output flexibility and noise immunity The output stage supports CMOS, push-pull, rail-to-rail, and TTL logic levels, so the same comparator can drive a microcontroller GPIO, a logic gate input, or a relay driver without an external pull-up resistor. The ±2.5 mV internal hysteresis prevents oscillation on slow-moving input signals — no external positive feedback network is needed for clean switching. Common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) are both 80 dB typical, meaning supply ripple and common-mode shifts couple weakly to the output decision. In a noisy industrial 24 V backplane stepped down to 3.3 V, the comparator's decision threshold stays stable within a few millivolts.","metaTitle":"MAX991EUA+ Analog Devices Comparator, 210ns, 2.5-5.5V","metaDescription":"MAX991EUA+ general-purpose dual comparator from Analog Devices. 210ns propagation delay, 96µA quiescent current, 1pA input bias.
