There are a number of filter options. Which one should I use?
The AD7176-2 has three filter options: Sinc5+Sinc1, Sinc3 and enhanced 50 & 60 Hz filters. The Sinc5+Sinc1 is most suited to multichannel applications where fast multiplexing is required. The Sinc3 is best for single channel applications running at lower output data rates. In applications where rejection of 50 and 60 Hz is important the enhanced 50 & 60 Hz rejection filters should be used as they provide better performance than the Sinc filters and allow the user to trade off settling time or rejection to meet their application needs. We provide a filter tool to help during design-in. See www.analog.com/AD7176-2
