Figure 7 Noninverting Comparator. Contact Hitachi’s sales office for any questions regarding this document or Hitachi semiconductor. Low input bias current: Then, when the A. This operation generates a square wave on Vout1 and a triangular wave on Vout2. Copyright ‘ Hitachi, Ltd.

HA Datasheet(PDF) – Hitachi Semiconductor

Extremely low current drain: Low output saturation voltage: The HA houses four independent comparators in a single package, and operates over a wide voltage range at low power from dataheet single-voltage power supply. Electrical Characteristics 1 V.

Figure 6 Basic Comparator. Figure 3 Pulse Generator. Products and product specifications may be subject to change without notice. This causes the integrator to ha117339 a negative state, resulting in its output decreasing towards the low level. These comparators have datxsheet unique characteristic of ground being included in the common-mode input voltage range, even when operating from a single-voltage power supply.


The HA and HA series products are comparators designed for use in power or control systems. With the circuit constants shown in figure 9.

This allows the pulse width and the duty cycle to be set independently. Figure 8 shows the input characteristics. Input offset voltage V.

The common-mode input voltage range includes ground. Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent. Low input offset current: Hitachi makes every attempt to ensure that its products are of high quality and reliability. Hitachi Asia Hong Kong Ltd. In the circuit in figure 5, comparator A.

Tokyo 03 Fax: Switched between ha173339 and 2. Input Bias Current I. 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. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

Figure 1 Square-Wave Oscillator. The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. Figure 4 Operating Waveforms.

When the input voltage V. Figure 4 shows the waveforms generated by this hx17339. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications. These products can be destroyed if the output and V. The circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator.

Input Bias Current vs. The circuit shown in figure 6 is a basic comparator.

If the output Vout1 is at. Figure 9 Inverting Comparator. Confirm that you have. With the circuit constants shown in figure 7.
