DP Conforms Conforms 0. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Input offset voltage V. Figure 4 shows the waveforms generated by this circuit. Frequency control voltage input. Tokyo 03 Fax: The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. FPDA — Conforms 0. Daasheet HA and HA series products are comparators designed for use in power or control systems.

Noninverting Comparator with Hysteresis. 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. Then, when the A. Hitachi Asia Hong Kong Ltd.


The circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator. In the circuit in figure 5, comparator A. Extremely low current drain: When the output of the integrator A. Figure 2 Operating Waveforms. The HA houses four independent comparators in a single package, and operates over a wide voltage range at low power from a single-voltage power supply. Low input offset current: This dqtasheet is not designed to be radiation resistant.

In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. Output Sink Current Iosink mA. Hitachi Semiconductor America Inc. This operation generates a square wave on Vout1 and a triangular wave on Vout2. Figure 2 shows the waveforms generated by this circuit. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications.

Figure 4 Operating Waveforms. Figure 11 Zero-Cross Detector.

These products can be destroyed if the output and V. Electrical Datasheey 1 V. With the circuit constants shown in figure 7. 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.

Figure 9 Inverting Comparator. D Feldkirchen, Munich Germany Tel: This section presents several sample HA applications. Figure 8 shows the input characteristics.

C above that temperature. Figure 7 Noninverting Comparator. Output Voltage Vout V.
