WM8903CLGEFK Overview
It is supplied in the 40-UFQFN Exposed Pad package for the purpose of space saving. It is adopted to package in the Tray way. The high-efficiency performance of this electronic part can be achieved in various applications due to its type of Stereo Audio. It employs Surface Mount as its mounting type. When the operating performance is set to -40°C~85°C, it can operate normally. It is integrated with 2 / 2 ADCs / DACs. There is a voltage supply of 1.71V~2V to the analog circuit. A supply voltage of 1.42V~3.6V is applied to the digital circuit. There are 40 terminations used to prevent signals from reflecting off the end of the transmission line. This device is mounted on a PCB which uses the Surface Mount technology. Supply voltage should never exceed 3.6V. It is possible to convert analog signals into digital signals using 2 A/D converters. Minimum supply voltage should remain at 950mV. There is no supply voltage for it.
