W681308DG Overview
A 48-LQFP package is supplied for space savings. It is adopted to package in the manner of Tray. This electronic component is of the type 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 1 / 1 ADCs / DACs. 3.13V~3.47V of supply voltage are applied to the analog circuit. A 3.13V~3.46V supply voltage is applied to the digital circuit. The transmission line is terminated with 48 terminations to prevent reflection of signals. This device consists of a row of 48-pins. This device is mounted on a PCB which uses the Surface Mount technology. Supply voltage should never exceed 3.47V. At a minimum, the voltage should be kept at 3.13V. When the supply voltage is 3.3V, it can operate.
