HA-4900, HA-4902, HA-4905 Precision Quad Comparators offer fast response time, low offset voltage, low offset current and virtually no channel-to-channel crosstalk for applications requiring accurate, high speed, signal level detection
The HA-4900 series are monolithic quad precision comparators offering fast response time, low offset voltage, low offset current and virtually no channel‑to‑channel crosstalk. They can operate from a single +5 V supply or dual supplies up to +15 V, and include a current‑driven output stage that directly matches standard logic levels without external components.
Typical applications include threshold detectors, zero‑crossing detectors, window detectors, analog interfaces for microprocessors, high‑stability oscillators and logic system interfaces. The datasheet also provides pin‑outs, absolute maximum ratings, electrical specifications, and example circuits such as logic level translators and Schmitt‑trigger based detectors.
