Dual comparator for threshold detection and signal conditioning
It compares two analog voltages per channel and outputs a logic-level signal via its open-drain MOS output stage. With a 4.5 µs propagation delay and 5 pA typical input bias current, it suits slow-to-moderate-speed threshold detection, zero-crossing detectors, window comparators, and sensor interface circuits where the input signal must not be loaded.
Low power draw and high input impedance
The 5 pA input bias at 5 V means the comparator presents essentially no load to a high-impedance source — think pH probe buffers, photodiode current thresholds, or resistive divider references that cannot tolerate a few nanoamps of leakage.
