In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. The A1 output will integrate this state and its output will increase towards the high level.

These products can be destroyed if the output and V. Even within the guaranteed ranges, consider normally foreseeable failure rates or failure modes in semiconductor devices and employ dqtasheet measures such as fail- safes, so that the equipment incorporating Hitachi product does not cause bodily injury, fire or other consequential damage ah17339 to operation of the Hitachi product.

In the circuit in figure 5, comparator A. Output voltages compatible with CMOS logic systems. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without.

For further information write to: The HA and HA series products are comparators designed for use in power or control systems.

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. Contact Hitachi’s sales office for any questions regarding this document or Hitachi semiconductor. This operation generates a square wave on Vout1 and a triangular wave on Vout2.

Figure 4 shows the waveforms generated by this circuit. Confirm that you have. Search field Part name Part description. If the output Vout1 is at.

Hitachi Semiconductor America Inc. A70mV 1mA. Figure 6 Basic Comparator.

Hitachi makes every attempt to ensure that its products are of high quality and reliability. The circuit shown in figure 6 is a basic comparator. Products and product specifications may be subject to change without notice. Figure 8 shows the input characteristics. Low output saturation voltage: Since the common-mode input voltage range starts at the ground datasheett, the HA is particularly suited for single-voltage power supply applications.
