Figure 4 Operating Waveforms. Figure 1 Square-Wave Oscillator. Electrical Characteristics 2 V. These comparators have the unique characteristic of ground being included in the common-mode input voltage range, even when operating from a single-voltage power supply. Eatasheet 8 shows the input characteristics.

Extremely low current drain: This datashete the pulse width and the duty cycle to be set independently. Switched between 1 and 2. A70mV 1mA. The HA and HA series products are comparators designed for use in power or control systems. Output voltages compatible with CMOS logic systems. Low output saturation voltage: Hitachi Asia Hong Kong Ltd.

Noninverting Comparator with Hysteresis. Dagasheet input offset voltage: Wide power-supply voltage range: These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-supply current since the power-supply voltage is determined independently.


This section presents several sample HA applications. This causes the integrator to integrate a negative state, resulting in its output decreasing towards the low level.

Figure 4 shows the waveforms generated by this circuit. Electrical Characteristics 1 V. For further information write to: The common-mode input voltage range includes ground. Confirm that you have.

No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Inverting Comparator with Hysteresis. Figure 3 Pulse Generator.

Figure 6 Basic Comparator. When the output of the integrator A. In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. The circuit shown in figure 6 is a basic comparator. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications.

Dtaasheet Semiconductor Datashedt Inc. Input offset voltage V. The A1 output will integrate this state and its output will increase towards the high level.
