PRODUCTION DATA.
As in single-ended applications, most systems can simply use an input filter similar to Figure 62. However, for systems with significant out-of-band noise, a simple filter such as that shown in Figure 63 can be used for pre-ADC, antialiasing filtering. The recommended resistor value for the antialiasing filter is 47 Ω. Place film-type capacitors of 0.01 µF as close as possible to the VINLx and VINRx pins, and terminate to GND as close as possible to the AGND pin in order to maximize the dynamic performance of ADC. To maintain common-mode rejection, match the series resistors as closely as possible.
