WM8731SEDS/V Overview
In order to save space, it is packaged in the 28-SSOP (0.209, 5.30mm Width) package. Tube packaging method is used. Due to the fact that this part is of the type Audio, it is capable of delivering high-efficiency performance in a wide range of applications. As a mounting type, it uses Surface Mount. When the operating performance is set to -40°C~85°C, it is able to operate normally. It features 2 / 2 ADCs / DACs. In the analog circuit, the supply voltage is 2.7V~3.6V. Supply voltage is set to 1.42V~3.6V for the digital circuit. There are 28 pins on this device. The chip is mounted to the PCB using the Surface Mount technology. Ideally, the supply voltage should remain at 3.6V. To convert analog signals into digital signals, there are 2 A/D converters. 2.7V should be the minimum value of supply voltage. Operating voltage of 3.6V is possible. Digital signals are converted into analog signals with 2 D/A converters. It is set to the maximum value of 85°C so normal use can be maintained. Keeping the operating temperature at -40°C will maintain regular use. There are 2 channels for transmitting data on it. The device is equipped with 3 analog inputs. A total of 6 analog outputs are included.
