WM8940CGEFL/RV Overview


For space-saving reasons, it is supplied in a 24-VFQFN Exposed Pad package. It is adopted to package in the manner of Tape & Reel (TR). The high-efficiency performance of this electronic part can be achieved in various applications due to its type of Audio. The mounting type is Surface Mount. When the operating performance is set to -25°C~85°C, the system can operate normally. It is equipped with a total of 1 / 1 ADCs and DACs. The analog circuit receives 2.5V~3.6V as a supply voltage. 1.71V~3.6V is the supply voltage for the digital circuit. To prevent signals from reflecting off of the transmission line, there are 24 terminations. This device consists of a row of 24-pins. The chip is mounted to the PCB using the Surface Mount technology. In order for the supply voltage to be maintained at 3.6V, it should be set to its maximum value. Converting analog signals to digital signals requires 1 A/D converters. It is recommended to maintain a voltage of 1.71V as the minimum value. There is no supply voltage for it.
