This causes the integrator to integrate a negative state, resulting in its output decreasing towards the low level. 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. Products and product specifications may be subject to change without notice.

With the circuit constants shown in figure 9. This operation generates a square wave on Vout1 and a triangular wave on Vout2. Then, when the A.

Output Sink Current Iosink mA. Tokyo 03 Fax: These products can be destroyed if the output and V. Electrical Characteristics 1 V. Wide power-supply voltage range: Figure 4 Operating Waveforms. Input Bias Current vs. Output saturation voltage V.

Frequency control voltage input. Output Sink Current vs. This section presents several sample HA applications.

Contact Hitachi’s sales office for any questions regarding this document or Hitachi semiconductor. The HA and HA series products are comparators designed for use in power or control systems. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications.

Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. With the circuit constants shown in figure 7. Confirm that you have. Search field Part name Part description.

The common-mode input voltage range includes ground. C above that temperature.

Input offset voltage V. Low input offset current: DP Conforms Conforms 0. Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. Output voltages compatible with CMOS logic systems.

D Feldkirchen, Munich Germany Tel: The stipulated response time is the value for a mV input step voltage that ha177339 a 5mV. Low output saturation voltage: This allows the pulse width and the duty cycle to be set independently. Noninverting Comparator with Hysteresis.


These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-supply current since datasgeet power-supply voltage is determined independently. This product is not designed to be radiation fatasheet. 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.
