APPLICATION INFORMATION
fully differential configuration
In this configuration, the ADC converts the difference (
IN) of the two input signals on IN+ and IN–.

Figure 16. Differential Input
The resistors and capacitors on the inputs decouple the driving source output from the ADC input and also serve
as first order low pass filters to attenuate out of band noise.
The input range on both inputs is 0 V to AVDD. The full-scale value is determined by the voltage reference. The
positive full-scale output is reached, if
IN equals REF, the negative full-scale output is reached, if IN equals
–
REF.

transformer coupled single-ended to differential configuration
If the application requires the best SNR, SFDR, and THD performance, the input should be transformer coupled.
The signal amplitude on both inputs of the ADC is one half as high as in a single-ended configuration thus
increasing the ADC ac performance.

n = 1 (winding ratio)
The resistor R of the transformer coupled input configuration must be set to match the signal source impedance
R = n2 Rs, where Rs is the source impedance and n is the transformer winding ratio.
