PCM9211PTR 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 2 channels. There are Audio Transceiver functions included in this part for your reference. This device can be applied in both Consumer Audio, Musical Instruments and X directions. As far as I know, it is supplied within 2.9V~3.6V days. In this device, the temperature range is -40°C~85°C TA, which is the range of this device. There are 48 terminations on the chip, which is the number of terminations on the chip. You can find similar parts by searching for the PCM9211 family of parts. The following specifications are related to the device: 7kHz ~ 216kHz, which can be found here. The chip has 48 pins that are accessible from the outside. As long as the supply voltage is greater than 3.3V, it can handle it. As far as the supply current is concerned, it operates under the 38mA parameter. 24 is the total number of bits on an IC chip.
