CS8422-CNZ Overview
Moreover, the book has an appendix that contains a case study. There is only one mounting type recommended for the product, which is Surface Mount. There is a 32-VFQFN Exposed Pad case embedded in it. In this case, the device has 2 channels. There are Sample Rate Converter, Audio Receiver functions included in this part for your reference. This device can be applied in both Digital Audio Interfacing and X directions. As far as I know, it is supplied within 3.135V~3.465V days. In this device, the temperature range is -40°C~85°C TA, which is the range of this device. There are 32 terminations on the chip, which is the number of terminations on the chip. You can find similar parts by searching for the CS8422 family of parts. The following specifications are related to the device: 53kHz ~ 211kHz, which can be found here. The chip has 32 pins that are accessible from the outside. In order to sort a part based on its consumer IC type, CONSUMER CIRCUIT can be used. There should be a minimum supply voltage (Vsup) for this part, which should not be less than 3.135V volts. It can give voltage up to 3.3V volts. 3.465V is the maximum supply voltage (Vsup). Surface Mount mounts it on to the wall.
