WM8731CLSEFL Overview
For space-saving reasons, it is supplied in a 28-VFQFN Exposed Pad package. We have adopted the packaging method of Tube. Its Audio type ensures high-efficiency performance in a range of applications. A mounting type of Surface Mount is used for this device. A performance setting of -40°C~85°C allows it to operate normally. 2 / 2 ADCs and DACs are integrated into it. Supply voltage is 1.8V~3.6V for the analog circuit. 1.42V~3.6V provides the supply voltage to the digital circuit. Signals are prevented from reflecting off the end of transmission lines by 28 terminations. An integrated circuit is mounted on a PCB based on the technology of Surface Mount. In order for the supply voltage to be maintained at 3.6V, it should be set to its maximum value. It is recommended that the supply voltage is maintained at 1.8V.
