WM8994ECS/R Overview
A 72-WFBGA, CSPBGA package is supplied for space savings. It is adopted to package in the manner of Tape & Reel (TR). This electronic component is of the type Stereo Audio, allowing it to provide high-efficiency performance in various applications. This device employs the mounting type Surface Mount. When the operating performance is set to -40°C~85°C, the system can operate normally. The unit is integrated with 2 / 4 ADCs / DACs. 1.71V~2V of supply voltage are applied to the analog circuit. A 1.62V~3.6V supply voltage is applied to the digital circuit. The transmission line is terminated with 72 terminations to prevent reflection of signals. This device consists of a row of 72-pins. This device is mounted on a PCB which uses the Surface Mount technology. Supply voltage should never exceed 3.6V. As a result of analog signals being converted into digital signals, there are 2 A/D converters. At a minimum, the voltage should be kept at 950mV. A voltage of 1V is required to operate the device. When the supply voltage is 3.6V, it can operate. Data transmission is achieved through 4 channels. 8 analog inputs are available on this device. A total of 9 analog outputs are available on the device.
