Technical Information (continued)
[2] Application note (continued)
10. Beep sound input function
1) The application circuit using the beep sound input is shown in figure 7. Connect the beep signals from the
microcomputer to pin 10 via the capacitor C1 for DC cut and the resister R1 for voltage gain adjustment.
2) The voltage gain of beep sound terminal is approx. 3.4 dB. With settings shown in the following drawing, it
is approx.
12.7 dB (f
=
1 kHz).
3) The beep sound is outputted to output terminals pin 2 and pin 15 only.
