Quad comparator with built-in hysteresis for threshold detection
The Maxim Integrated MAX995EUD+ is a quad general-purpose comparator in a 14-TSSOP surface-mount package.
The built-in ±2.5 mV hysteresis eliminates the need for external positive feedback resistors to prevent output chatter near the threshold, saving two resistors per channel and simplifying the layout.
Low quiescent current for power-sensitive BOMs
The quiescent current is specified at 96 µA maximum for all four comparators combined. That is roughly 24 µA per channel, which keeps the power budget tight in battery-operated or always-on sensor nodes. The input bias current is just 1 pA at 5.5 V, so high-impedance sources like photodiode amplifiers or pH probes see negligible offset error from the comparator input.
