Dual comparator with 9 ns propagation delay
The Maxim Integrated MAX9012EUA+ is a dual-channel general-purpose comparator in an 8-uMAX/uSOP package. It delivers a 9 ns maximum propagation delay, making it suitable for high-speed signal detection, zero-crossing detectors, and fast overcurrent or overvoltage fault comparators in industrial control and test equipment. Input offset voltage is specified at 3 mV maximum at 5.5 V, and input bias current stays under 0.5 µA at 5 V. Common-mode rejection is 95 dB typical, power-supply rejection 82 dB typical — both help maintain threshold accuracy in noisy industrial environments.
The 8-uMAX/uSOP (3.00 mm body width, 0.65 mm pitch) is a compact fine-pitch package. The small thermal mass means it reflows quickly — a standard lead-free profile with a 240°C peak works fine, but watch the ramp rate to avoid tombstoning. The part is MSL 1 per the ROHS3 compliance status, so no bake is required before reflow as long as the bag seal is intact.
For new designs or BOM fill, the MAX9012EUA+ is a straightforward, no-timeline-pressure choice.
