WM8731CLSEFL/R Overview
A 28-VFQFN Exposed Pad package is provided to save space. It is adopted to package in the Tape & Reel (TR) way. In numerous applications, this electronic part can deliver high-efficiency performance as a type of Audio. The mounting type is Surface Mount. When the operating performance is set to -40°C~85°C, it can operate normally. The board is integrated with 2 / 2 ADCs and DACs. A supply voltage of 1.8V~3.6V is applied to the analog circuit. A supply voltage of 1.42V~3.6V is applied to the digital circuit. Transmission lines have 28 terminations to prevent signals from reflecting. Using the Surface Mount technology, it is mounted to a PCB. 3.6V should be the maximum value of the supply voltage. Analog signals are converted into digital signals using 2 A/D converters. A minimum supply voltage of 1.8V should be maintained.
