Bipolar (

5 V) Configuration
T he AD7233 provides an output voltage range from –5 V to
+5 V without any external components. T his configuration is
shown in Figure 4. T he data format is 2s complement. T he out-
put code table is shown in T able I. If offset binary coding is re-
quired, then this can be done by inverting the MSB in software
before the data is loaded to the AD7233.

Power Supply Decoupling
T o achieve optimum performance when using the AD7233, the
V
DD
and V
SS
lines should each be decoupled to GND using
0.1
μ
F capacitors. In very noisy environments it is recom-
mended that 10
μ
F capacitors be connected in parallel with the
0.1
μ
F capacitors.
