FOperation notes

(1) Precautions concerning the load resistance

The various characteristics were measured at the output

resistance value of 10MΩ noted in the specifications

manual. Moreover, because the output of this IC sup-

ports the MOS configuration, be aware that it is current

output, and the output changes depending on the input

impedance at the next stage.

(2) Precautions concerning the RESET capacitor

If the reset function is to be used, a capacitor of at least

3300pF is required for RESET C (pin 7). Failing to con-

nect this capacitor can result in erroneous displays, so

make sure a sufficient capacitance is provided.

(3) Precautions concerning the coupling capacitor

When determining the polarity of the input electrolytic

coupling capacitor, the potential relation with the other

end of the coupling must be taken into consideration.
