The reference is on-chip, so the threshold accuracy tracks with the comparator's own offset rather than an external resistor divider. The dual-supply option (±1.25 V to ±2.75 V) lets it sit in a split-rail analog front-end if needed. Input bias current is 1 pA max at 5 V — this is the figure that matters for high-impedance sensor interfaces. A 10 MΩ source resistance sees only 10 µV of voltage error from bias current, so the comparator does not load the signal. The 1 mV max input offset at 5 V sets the DC accuracy floor for the threshold. Propagation delay is 450 ns max, which limits the comparison rate to roughly 2.2 MHz before the output fails to settle. For a 100 kHz PWM current-sense or a 400 kHz switching regulator feedback loop, this delay is well within the timing budget. ## Output drive and noise immunity for industrial signal chains The output stage is CMOS push-pull with rail-to-rail swing and TTL-compatible levels, so it drives logic inputs directly without a pull-up resistor. Typical output current is 8 mA, enough to sink a standard LED indicator or a 5 V CMOS load. CMRR and PSRR are both 80 dB typical. That 80 dB of common-mode rejection means a 1 V common-mode shift at the input produces only 100 µV of apparent offset — relevant when the comparator sees a noisy ground or a floating sensor. The 80 dB PSRR keeps supply ripple from coupling into the comparison threshold. Built-in hysteresis of ±3 mV prevents output chatter when the input signal sits near the threshold. Without this, a slow-moving or noisy signal would toggle the output on every noise spike; the 3 mV band creates a clean switch point. ## Temperature grade and package for production assembly A motor-drive enclosure that sees 70°C internal ambient still has 15°C of margin before the part leaves its guaranteed range. Supplied in Tube packaging, which is the standard antistatic tube for MSOP-family devices. For reel-fed pick-and-place, request the tape-and-reel variant if available; the tube format is better suited to low-volume or prototype builds.","metaTitle":"MAX9043BEUB+ Dual Comparator with Voltage Reference, 450ns","metaDescription":"MAX9043BEUB+ dual comparator with integrated voltage reference.
