AD1981AJST-REEL Overview
A 48-LQFP package is provided to save space. It is adopted to package in the Tape & Reel (TR) way. In numerous applications, this electronic part can deliver high-efficiency performance as a type of Audio Codec '97. The mounting type is Surface Mount. When the operating performance is set to 0°C~70°C, it can operate normally. The board is integrated with 4 / 2 ADCs and DACs. A supply voltage of 4.65V~5.25V is applied to the analog circuit. A supply voltage of 3.15V~3.45V is applied to the digital circuit. Transmission lines have 48 terminations to prevent signals from reflecting. There are 48 pins on it. A minimum supply voltage of 4.65V is supported. Voltages up to 5.25V can be supplied to it. There are a variety of applications for this electronic part from the SoundMAX® series.
