Quad comparator with 450ns propagation delay and 24µA quiescent current
The MAX993ESD+T is a quad general-purpose comparator from Maxim Integrated. Key parametric limits: 450ns max propagation delay, 24µA max quiescent current per device, 1pA max input bias current at 5.5V, and 5mV max input offset voltage at 5.5V. The ±3mV built-in hysteresis cleans up noisy zero-crossing signals without external feedback. Single-supply range is 2.5V to 5.5V, with dual-supply operation from ±1.25V to ±2.75V. The 80dB typical CMRR and PSRR keep offset errors low across the common-mode and supply range — relevant for precision threshold detection in battery-powered or low-voltage systems.
