AD7226
OFFSET ADJUST
Figure 17 shows how the AD7226 can be used to provide pro-
grammable input offset voltage adjustment for the AD544 op
amp. Each output of the AD7226 can be used to trim the input
offset voltage on one AD544. The 620 k
W resistor tied to 10 V
provides a fixed bias current to one offset node. For symmetri-
cal adjustment, this bias current should equal the current in the
other offset node with the half-full scale code (i.e., 10000000)
on the DAC. Changing the code on the DAC varies the bias
current and hence provides offset adjust for the AD544. For
example, the input offset voltage on the AD544J, which has a
maximum of
±2 mV, can be programmably trimmed to ±10 mV.
