WM8940CGEFL/RV Overview
Due to space constraints, it is supplied in the 24-VFQFN Exposed Pad package. This package uses the Tape & Reel (TR) packaging method. This electronic part is categorized as a type of Audio, making it capable of providing high-efficiency performance in a variety of applications. Surface Mount is the mounting type employed by this device. Operating performance -25°C~85°C permits it to function normally. In addition, it is equipped with 1 / 1 ADCs and DACs. The analog circuit receives 2.5V~3.6V as a supply voltage. It receives a voltage of 1.71V~3.6V as its supply voltage. In order to prevent signal reflections from off the end of the transmission line, 24 terminations are used. Essentially, it is an electronic device with 24 pins. Based on the Surface Mount technology, the module is mounted to a PCB. 3.6V is the maximum value of supply voltage. Analog signals are converted to digital signals by means of 1 A/D converters. Minimum supply voltage should remain at 1.71V. There is 1.8V supply voltage for this device.
