The AD4170-4 has several filter options; Sinc5 + AVg, Sinc3, Sinc5, Post (FIR) Filter, Wideband FIR Filter, and Programmable Wideband FIR Filter. The filter type selection affects the rms noise, the 50/60 Hz rejection, the settling time, stopband attenuation and AC performance. So, a trade-off is needed among the different parameters. The Sinc filters are good for DC inputs, designs requiring low latency, and multiplexed applications. With the Sinc3 and Sinc5 filters, the noise performance is similar at the lower output data rates. Hence, the AD4170-4 provides the Sinc3 filter only at the low output data rates. At the higher output data rates, the higher order Sinc filter gives better noise performance. So, the Sinc5 filter is selectable at these higher output data rates to reject the noise more effectively. These filters can be selected on a per channel basis when using the sequencer and can also be programmed to provide simultaneous 50 Hz and 60 Hz rejection. The FIR filter is suitable for AC inputs. The FIR filter has low pass-band ripple, quick roll-off and good stop-band attenuation. Therefore, it is the optimum choice for AC inputs. The FIR filter has a long settling time. Note that the FIR filter can be used when a single channel only is enabled. It cannot be used when the sequencer is used.
