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.

HA17339A Application Notes

1. Square-Wave Oscillator

The circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator.
