APPLICATION INFORMATION
data converters
Data converters are one of the most popular applications for the fully differential amplifiers. The following
schematic shows a typical configuration of a fully differential amplifier attached to a differential ADC.

Figure 30. Fully Differential Amplifier Attached to a Differential ADC
Fully differential amplifiers can operate with a single supply. V
OCM
defaults to the midrail voltage, V
CC
/2. The
differential output may be fed into a data converter. This method eliminates the use of a transformer in the circuit.
If the ADC has a reference voltage output (V
ref
), then it is recommended to connect it directly to the V
OCM
of
the amplifier using a bypass capacitor for stability. For proper operation, the input common-mode voltage to the
input terminal of the amplifier should not exceed the common-mode input voltage range.
