HA17339A Series
HA17339A Application Examples
The HA17339A houses four independent comparators in a single package, and operates over a wide voltage range at
low power from a single-voltage power supply. Since the common-mode input voltage range starts at the ground
potential, the HA17339A is particularly suited for single-voltage power supply applications. This section presents
several sample HA17339A applications.
