HA17901 Application Examples
The HA17901 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 HA17901 is particularly suited for single-voltage power supply applications.
This section presents several sample HA17901 applications.
HA17901 Application Notes
1. Square-Wave Oscillator
The circuit shown in figure one has the same structure as a single-voltage power supply astable
multivibrator. Figure 2 shows the waveforms generated by this circuit.
