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.
In applications that are sensitive to power-supply noise,
decouple V
value to that of the C1A and C1B charge-pump capaci-
tors. Connect the bypass capacitor as close as possi-
ble to the V
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.
