The Maxim MAX996ESD+ is a general-purpose quad comparator in a 14-SOIC surface-mount package. Each channel delivers a 210 ns typical propagation delay, which is fast enough for threshold detection, zero-crossing, and window-comparator circuits in industrial control loops and power-supply monitoring. The 96 µA maximum quiescent current across all four channels makes it a strong candidate for battery-powered instrumentation and field-transmitter designs where every microamp counts.
The 210 ns propagation delay is the time from the input crossing the threshold to the output switching.
Supply range and output flexibility
The part operates from a single 2.5 V to 5.5 V supply, or split supplies of ±1.25 V to ±2.75 V.
The 80 dB typical CMRR and PSRR provide reasonable rejection of common-mode noise and supply ripple in these electrically noisy settings.
There is no LTB notice or obsolescence risk on this line. For dual-sourcing resilience, the MAX996ESD (without the + suffix) is the same die in the same package; the + denotes ROHS3 compliance, so the MAX996ESD+ is the preferred ordering code for new lead-free builds.
