There is also an accompanying case included with this set. The mounting type recommended by the manufacturer is Surface Mount. A 24-SOIC (0.295, 7.50mm Width) case contains it. In this case, the device has 1 channels. There are Audio Transmitter functions included in this part for your reference. This device can be applied in both Digital Audio Interfacing and X directions. Votage within 3V~3.6V is supplied. This device operates temperature at the range of 0°C~70°C TA. 24 is the number of terminations on the chip. If you search for the STA020 family, you will find similar parts. I would like you to refer to the related specifications of the device: 96kHz. The chip has 24 pins that are accessible from the outside. Surface Mount mounts it on to the wall. The chip conducts in a 3.3V-voltage supply. A supply voltage of 3.3V can be applied to it.
