Typical Applications
12-Bit Successive Approximation A-to-D Converter,
Operating in Continuous 8–Bit Truncated Mode
12-Bit Successive Approximation A-to-D Converter, Operating in
Continuous Mode, Drives the 50k/100k Ladder Network Directly
Definition of Terms
CP:
Register clock input.
CC:
Conversion complete
—this output remains at V
OUT(1)
during a conversion and goes to V
OUT(0)
when conversion
is complete.
D:
Serial
data
input—connected to comparator output in A-
to-D applications.
E:
Register enable
—this input is used to expand the
length of the register. When E is at V
IN(1)
Q11 is forced to
V
OUT(1)
and inhibits conversion. When not used for expan-
sion E must be connected to V
IN(0)
(GND).
Q11:
True register MSB output.
Q11:
Complement of register MSB output.
Qi (i
=
0 to 11):
Register outputs.
S:
Start input
—holding start input at V
IN(0)
for at least one
clock period will initiate a conversion by setting MSB (Q11)
at V
OUT(0)
and all other output (Q10–Q0) at V
OUT(1)
. If set-
up time requirements are met, a conversion may be initi-
ated by holding start input at V
IN(0)
for less than one clock
period.
DO:
Serial data output
—D input delayed by one clock
period.
