Input Bias Current I.

View ha17339 datasheet:

When the input voltage V. Output Voltage Vout V. Since the common-mode input voltage range starts at the ground potential, the HA is particularly suited for single-voltage power supply applications.

Copyright ‘ Hitachi, Ltd. Figure 7 Noninverting Comparator. Contact Hitachi’s sales office for any questions regarding hz17339 document or Hitachi semiconductor. Figure 8 shows the input characteristics. Output Sink Current Iosink mA. When the output of the integrator A. The HA houses four independent comparators in a single package, and operates over a wide voltage range at low power from a single-voltage power supply.

Then, when the A. The A1 output will integrate this state and its output will increase towards the high level. Output Sink Current vs. Figure 2 Operating Waveforms. The common-mode input voltage range includes ground.

FPDA — Conforms 0.

Switched between 1 and 2. Daatsheet Conforms Conforms 0. Low input bias current: Figure 6 Basic Comparator. Low input offset voltage: Figure 4 Operating Waveforms. The charge and discharge circuits in the circuit from figure 1 are separated by diodes in this circuit.

Figure 1 Square-Wave Oscillator. Electrical Characteristics 1 V.

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. This operation generates a square wave on Vout1 and a triangular wave on Vout2.

The circuit shown in figure 6 is a basic comparator. Figure 3 Pulse Generator. These IC operate from a single power-supply voltage over a wide range of voltages, and feature a reduced power-supply current since the power-supply voltage is determined independently. A70mV 1mA. This product is not designed to be radiation resistant. Figure 2 shows the waveforms generated by this circuit.
