Is there a minimum number of SCLK for AD7476 in order to enter the power-down mode? Or can I high the CS after the second falling edge of the SCLK and disable the SCLK? Will the chip enter in power-down? The datasheet only says that to exit the power-down mode, you need to apply 10 SCLK and you can high the CS without 16 SCLK.
It is also said, if CS brought high before the 10 SCLK AD7476 go back to power-down mode. In this case, is it necessary to apply 16 SCLK to the chip when the CS is high?
Many thanks.
