Hitachi Semiconductor America Inc. Low input offset current: Figure 2 shows the waveforms generated by this circuit. The common-mode input voltage range includes ground. Input Bias Current vs. Contact Hitachi’s sales office for any questions regarding this document or Hitachi semiconductor. The circuit shown in figure datqsheet has the same structure dataaheet a single-voltage power supply astable multivibrator.

Low output saturation voltage: 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. Input offset voltage V. Input Bias Current I. Hitachi makes every attempt to ensure that its products are of high quality and reliability.


Wide power-supply voltage range: If the output Vout1 is at. Figure 8 shows the input characteristics. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Tokyo 03 Fax: A70mV 1mA. FPDA — Conforms 0. Output voltages compatible with CMOS logic systems. DP Conforms Conforms 0.

Figure 2 Operating Waveforms. In the circuit in figure 5, comparator A. Extremely low current drain: Output saturation voltage V.

Datasheeet the output of the integrator A. Figure 6 Basic Comparator. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications. In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V.

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. 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 section presents several sample HA applications. The HA houses four independent comparators datasheeh a single package, and operates over a wide voltage range at low power from a single-voltage power supply.

This operation generates a square wave on Vout1 and a triangular wave on Vout2. Low input bias current: Noninverting Comparator with Hysteresis.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. With the circuit constants shown in figure 7.
