PRODUCTION DATA
TI recommends placing an RC filter in front of the isolated amplifier to improve signal-to-noise performance of the signal path. Design the input filter such that:
Most voltage sensing applications use high-impedance resistor dividers in front of the isolated amplifier to scale down the input voltage. In this case, a single capacitor shown in Figure 8-2 is sufficient to filter the input signal.
