The HA houses four independent comparators in a single package, and operates over a ah17339 voltage range at low power from a single-voltage power supply. Figure 5 Voltage Controlled Oscillator. No one is permitted to reproduce or duplicate, in any form, the whole or part of this document without. Search field Part name Part description.

The stipulated response time is the value for a mV input step voltage that has a 5mV. Output voltages compatible with Ha1733 logic systems. Hitachi neither warrants nor grants licenses of any rights of Hitachi’s or any third party’s patent. The common-mode input voltage range includes ground. Switched between 1 and 2. Figure 1 Square-Wave Oscillator.

Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications. Hitachi makes every attempt to ensure that its products are of high quality and reliability. Hitachi Semiconductor America Inc. When the input voltage V.

Electrical Characteristics 1 V. This product is not designed to be radiation resistant. Figure 4 Operating Waveforms. Output saturation voltage V. The HA and HA series products are comparators designed for use in power or control systems.

The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit. Low input offset voltage: These comparators have the unique characteristic of ground being included in the common-mode input voltage range, even when adtasheet from a single-voltage power supply.

This allows the pulse width and the duty cycle to be set independently.

Hitachi bears no responsibility for failure or damage when used beyond the guaranteed ranges. DP Conforms Conforms 0.

Input Bias Current vs. Products and product specifications may be subject to change without notice. When the output of the integrator A. With the circuit constants shown in figure 9. Output Sink Current Iosink mA. Figure 7 Noninverting Comparator. A70mV 1mA. This section presents several sample HA applications. FPDA — Conforms 0. For further information write to: Low output saturation voltage: Output Sink Current vs. In the circuit in figure 5, comparator A.


These products can be destroyed if the output and V. Input offset voltage V. The circuit shown in figure one has the same structure as a single-voltage power supply astable multivibrator. Design your application so that the product is used within the ranges guaranteed by Hitachi particularly. Figure 3 Pulse Generator. Low input offset current: Input Bias Current I.

C above that temperature.

Noninverting Comparator with Hysteresis. In this circuit, the noninverting input will essentially beheld at the potential determined by dividing V. This causes the integrator to integrate a negative state, resulting in its output decreasing towards the low level.
