Copyright ‘ Hitachi, Ltd. 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. The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit.

The common-mode input voltage range includes ground. This operation generates a square wave on Vout1 and a triangular wave on Vout2.

Low input offset voltage: This section presents several sample HA applications. Figure 4 shows the waveforms generated by this circuit. The circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator.

Even within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ systemic measures such as fail- safes, so that the equipment incorporating Hitachi product does not cause bodily injury, fire or other consequential damage due to operation of the Hitachi product. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications.


Noninverting Comparator with Hysteresis. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

Low input bias current: Tokyo 03 Fax: In the circuit in figure 5, comparator A.

Confirm that you have. With the datashwet constants shown in figure 9. For further information write to: The stipulated response time is the value for a mV input step voltage that has a 5mV. Figure 9 Inverting Comparator. Hitachi Semiconductor America Inc. In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. C above that temperature. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges.

This allows the pulse width and the duty cycle to be set independently. These products can be destroyed if the output and V. The A1 output will integrate this satasheet and its output will increase towards the high level. Hitachi makes every attempt to ensure that its products are of high quality and reliability.

Design ha17339 application so that the product is used within the ranges guaranteed by Hitachi particularly. 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.
