and X7R ceramic capacitors are recommended for
operation over the full temperature range.
Larger capacitors may be used for C2 and C4 (see
Typical Operating Circuit) to reduce ripple on the trans-
mitter output voltages.
Power-Supply Decoupling
In applications that are sensitive to power-supply noise,
decouple VCC to ground with a capacitor similar in
value to that of the C1A and C1B charge-pump capaci-
tors. Connect the bypass capacitor as close as possi-
ble to the VCC and GND pins.
V+ and V- as Power Supplies
A small amount of power can be drawn from V+ and V-.
Excessive loads will cause V+ and V- to fall out of
regulation. When V+ or V- are loaded, check for good
regulation over the intended operating temperature
range.
