AK4122AVQ 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 48-LQFP case embedded in it. In this case, the device has 1 channels. There are Sample Rate Converter 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 3V~3.6V days. In this device, the temperature range is -10°C~70°C TA, which is the range of this device. The following specifications are related to the device: 8kHz ~ 96kHz, which can be found here. The chip has 48 pins that are accessible from the outside. Packaged by 48-LQFP (7x7), the device is available for purchase. It is recommended that you use this feature when the temperature is below 70°C degrees. Chips are operated at a temperature no lower than -10°C, which is the minimum operating temperature.
