We are using the AD7176-2 to collect a sequence of samples but we want an external microprocessor to time the sampling. Sample rate will be in the 4 kHz to 5 kHz range but the sample timing needs to be coordinated with stepper motor control and rotating mechanical parts -- e.g., we want N samples for every rotation. Can we use the AD7176-2 SYNC input to time sampling with the AD7176-2 in single cycle mode? If the SYNC is toggled at around 5 kHz, what settings should be used in the FILTCONx register? (Output Data Rate = 5000 or 10000? Filter Type = Sinc5 to reduce settling time?) Any advice you can provide would be appreciated.
