WM8731CLSEFL/R Overview
Space-saving is achieved by supplying it in the 28-VFQFN Exposed Pad package. We have adopted the packaging method of Tape & Reel (TR). It can perform highly efficiently in various applications since it is a type of Audio. The mounting type of this device is Surface Mount. Using -40°C~85°C as the operating performance allows it to operate normally. It features 2 / 2 ADCs / DACs. The analog circuit receives 1.8V~3.6V as a supply voltage. It receives a voltage of 1.42V~3.6V as its supply voltage. In order to avoid reflections off the end of the transmission line, 28 terminations are used. It is mounted to a PCB based on the Surface Mount technology. Voltage should not exceed 3.6V. Converting analog signals to digital signals requires 2 A/D converters. Minimum supply voltage should remain at 1.8V.
