The MAX917EUK+T is a single comparator from Analog Devices' Beyond-the-Rails™ series, integrating a voltage reference on-chip. It combines a 4mV hysteresis comparator with a rail-to-rail CMOS output stage, drawing a maximum quiescent current of 1.6µA. Supply range spans 1.8V to 5.5V single or dual supply, suiting battery-operated and low-voltage rail monitoring. The 95µs max propagation delay is adequate for slow-changing threshold detection like over-voltage or under-voltage lockout circuits.
Supply and signal characteristics
Input offset voltage is 5mV max at 5V, with input bias current of 0.001µA max at 5V — negligible for high-impedance sensor interfaces. PSRR is 80dB typical, maintaining threshold accuracy across supply ripple. The output can sink or source 50mA typical, enough to drive a logic input or a small load directly.
