APPLICATIONS INFORMATION
Figure A illustrates use of the on–chip level converter
detailed in Figure 2. The 0–to–5 volt Digital Control signal
is used to directly control a 9 V
p–p
analog signal.
The digital control logic levels are determined by V
DD
and V
SS
. The V
DD
voltage is the logic high voltage; the V
SS
voltage is logic low. For the example, V
DD
= + 5 V = logic
high at the control inputs; V
SS
= GND = 0 V = logic low.
The maximum analog signal level is determined by V
DD
and V
EE
. The V
DD
voltage determines the maximum
recommended peak above V
SS
. The V
EE
voltage
determines the maximum swing below V
SS
. For the
example, V
DD
– V
SS
= 5 volt maximum swing above V
SS
;
V
SS
– V
EE
= 5 volt maximum swing below V
SS
. The
example shows a
±
4.5 volt signal which allows a 1/2 volt
margin at each peak. If voltage transients above V
DD
and/or
below V
EE
are anticipated on the analog channels, external
diodes (D
x
) are recommended as shown in Figure B. These
diodes should be small signal types able to absorb the
maximum anticipated current surges during clipping.
The absolute maximum potential difference between
V
DD
and V
EE
is 18.0 volts. Most parameters are specified
up to 15 volts which is the recommended maximum
difference between V
DD
and V
EE
.
Balanced supplies are not required. However, V
SS
must
be greater than or equal to V
EE
. For example, V
DD
=
+ 10 volts, V
SS
= + 5 volts, and V
EE
= – 3 volts is acceptable.
