• See page 15 for IC Block Diagrams.
Note on Schematic Diagram:
• All capacitors are in µF unless otherwise noted.
pF: µµF 50 WV or less are not indicated except
for electrolytics and tantalums.
• All resistors are in
Ω
and
1
/
4
W or less unless
otherwise specified.
•
A
: B+ Line.
• Power voltage is dc 2.4 V and fed with regu-
lated dc power supply from battery terminal.
• Voltages are taken with a VOM (Input imped-
ance 10 M
Ω
).
Voltage variations may be noted due to normal
production tolerances.
• Signal path.
