APPLICATIONS INFORMATION
DIFFERENTIAL OUTPUT
In certain applications, it is necessary to create a differential
signal. High resolution analog-to-digital converters often require a
differential input. In other cases, transmission over a long distance
can require differential signals for better immunity to interference.
Figure 61 shows how to configure the AD8253 to output a
differential signal. An op amp, the AD8675, is used in an
inverting topology to create a differential voltage. VREF sets the
output midpoint according to the equation shown in the figure.
Errors from the op amp are common to both outputs and are
thus common mode. Likewise, errors from using mismatched
resistors cause a common-mode dc offset error. Such errors are
rejected in differential signal processing by differential input
ADCs or instrumentation amplifiers.
When using this circuit to drive a differential ADC, VREF can be
set using a resistor divider from the ADC reference to make the
output ratiometric with the ADC.
