13.11 8-BIT ADC CHARACTERISTICS
TA = -40°C to 125°C, unless otherwise specified
Figure 88. Typical Application with ADC
Notes:
1. Any added external serial resistor will downgrade the ADC accuracy (especially for resistance greater than 10k
). Data
based on characterization results, not tested in production.
2. The stabilization time of the AD converter is masked by the first tLOAD. The first conversion after the enable is then
always valid.
13.11.0.1 General PCB Design Guidelines
To obtain best results, some general design and
layout rules should be followed when designing
the application PCB to shield the the noise-sensi-
tive, analog physical interface from noise-generat-
ing CMOS logic signals.
– Properly place components and route the signal
traces on the PCB to shield the analog inputs.
Analog signals paths should run over the analog
ground plane and be as short as possible. Isolate
analog signals from digital signals that may
switch while the analog inputs are being sampled
by the A/D converter. Do not toggle digital out-
puts on the same I/O port as the A/D input being
converted.
