AS339/339A LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS Description Pin Assignments The AS339/339A consist of four independent precision voltage comparators with a typical offset voltage of 2.0mV and high gain. (Top View) They are specifically designed to operate from a single power supply over wide range of voltages. Operation from split power supply is also OUTPUT 2 14 OUTPUT 3 1 possible and the low power supply current drain is independent of the magnitude of the power supply voltage. OUTPUT 4 OUTPUT 1 2 13 The AS339/339A series are compatible with industry standard 339. V 3 12 GND CC The AS339A has more stringent input offset voltage than the AS339. INPUT 4+ INPUT 1- 11 4 The AS339 is available in SO-14 and TSSOP-14 packages, and the 10 INPUT 4- INPUT 1+ 5 AS339A is available in SO-14 package.
