The TS393 is a micropower CMOS dual voltage comparator with extremely low consumption of 9µA typ / comparator (20 times less than bipolar LM339).
The TS393 is a micropower dual CMOS voltage comparator offering extremely low supply current, low input bias and offset currents, and a wide single‑supply voltage range of 2.7 V to 16 V. It is pin‑to‑pin compatible with the bipolar LM393 and is available in several ECOPACK® packages.
