FIGURE 8. Two Channel Multiplexed Operation Connection Diagram
Best converter performance is achieved when these inter-
nal bypass capacitors are supplemented with additional ex-
ternal power-supply decoupling capacitors. This ensures the
lowest ac-bypass impedance path for the ADC16071/
ADC16471’s dynamic current requirements. Each of the
ADC16071/ADC16471’s four supply pins should be individ-
ually bypassed, using a parallel combination of 10
m
F (tan-
talum) and 0.1
m
F (monolithic ceramic), to its corresponding
ground pin:

Short lead lengths are mandatory. Therefore, surface mount
capacitors are
strongly
recommended.
POWER SUPPLY VOLTAGES FOR BEST
PERFORMANCE
While adequate performance will be achieved by operating
the ADC16071/ADC16471 with
a
5V connected to V
A
a
,
V
M
a
and V
D
a
, dynamic performance, as measured by
S/(N
a
D), can be further enhanced by slightly raising the
analog supply voltage and lowering the digital supply volt-
age.
ANALOG INPUT
The ADC16071 and the ADC16471 generate a two’s com-
plement output determined by the following equation:
Output Code
e
(V
IN
a b
V
IN
b
) (32768)
(V
REF
a b
V
REF
b
)
Round off to the nearest integer value between
b
32768
and 32767.
The signals applied to V
IN
a
and V
IN
b
must be between
V
A
a
and analog ground. For accurate conversions, the ab-
solute difference between V
IN
a
and V
IN
b
should be less
than the difference between V
REF
a
and V
REF
b
. Best har-
monic performance will result when a differential voltage is
applied to V
IN
a
and V
IN
b
that has a common mode voltage
at or below V
MID
.
Due to overloading in the ADC16071/ADC16471’s
DR
mod-
ulator, performance degrades considerably as the input am-
plitude approaches full scale. With an input that peaks at
b
2 dB from full scale, S/(N
a
D) is about 2 dB worse than
with a
b
6 dB input. With a
b
1 dB input, S/(N
a
D) can be
10 dB worse than with a
b
6 dB input.
