The Maxim Integrated MAX9202EUD+ is a dual-channel comparator with a latch function, meaning each comparator's output state can be frozen on a strobe signal and held until the next latch enable. The two elements share a common supply and ground, so a single 14-TSSOP package handles two independent threshold decisions. Outputs are TTL-compatible, which simplifies interfacing to 5V logic families or a microcontroller's GPIO without level translation. The supply range spans 4.75V to 10.5V on a single rail, or ±2.375V to ±5.75V on split supplies — useful when the comparator sits between an analog front-end and a digital controller running on different rails. Typical CMRR and PSRR both sit at 86.02 dB, giving the part decent rejection of common-mode noise and supply ripple.
Package, temperature grade, and supply — the design-in constraints
The 14-TSSOP body (4.40 mm wide, 0.173" pitch) is a fine-pitch surface-mount package. The PCB layout engineer should note the narrow lead pitch — a standard 0.65 mm TSSOP footprint works, but the soldermask web between pads is tight. Quiescent current is listed as 4 mA, 3 mA, 1.5 mA.
