AD7233–Typical Performance Characteristics
APPLYING THE AD7233
Bipolar ( 5 V) Configuration
The AD7233 provides an output voltage range from –5 V to
+5 V without any external components. This configuration is
shown in Figure 4. The data format is two’s complement. The
output code table is shown in Table I. If offset binary coding is
required, it can be done by inverting the MSB in software before
the data is loaded to the AD7233.
Power Supply Decoupling
To achieve optimum performance when using the AD7233, the
V
0.1 µF capacitors. In very noisy environments it is recom-
mended that 10 µF capacitors be connected in parallel with
the 0.1 µF capacitors.
