Comparators

Simplified solutions without compromise

parametric-filterView all products
Whether you need ultra-low-power comparators for extending battery life, high-speed comparators for fast response in critical timing measurement applications, high-voltage comparators with wide operating range for greater detection capability, or low-voltage comparators for precision in sensitive applications, our innovative portfolio provides you with versatility to design. Our comparators are specialized for industrial, automotive, and aerospace applications, and can provide over-voltage, under-voltage, and current monitoring solutions, or more specific solutions like zero cross detection.
