Product Brief

LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS

AZ339

Description

The AZ339 series consists of four independent precision

voltage comparators with an offset voltage specification as

low as 2mV. The input common mode voltage range of

these comparators includes ground, even when operated

from a single power supply voltage. Operation from split

power supplies is also possible and the low power supply

current drain is independent of the magnitude of the power

supply voltage. The AZ339 series is designed to directly

interface with TTL and CMOS.
