AD1939YSTZRL Overview
In order to save space, it is packaged in the 64-LQFP package. Tape & Reel (TR) packaging method is used. Due to the fact that this part is of the type General Purpose, it is capable of delivering high-efficiency performance in a wide range of applications. As a mounting type, it uses Surface Mount. When the operating performance is set to -40°C~105°C, it is able to operate normally. It features 4 / 8 ADCs / DACs. In the analog circuit, the supply voltage is 3V~3.6V. Supply voltage is set to 3V~3.6V for the digital circuit. 64 terminations prevent signals from reflecting off transmission lines. There are 64 pins on this device. 64 pins are connected to it. More related parts can be found using its base part number AD1939. The chip is mounted to the PCB using the Surface Mount technology. Ideally, the supply voltage should remain at 5V. To convert analog signals into digital signals, there are 4 A/D converters. 3.3V should be the minimum value of supply voltage. The supply voltage is set to 3.3V. Digital signals are converted into analog signals with 8 D/A converters. The storage of information is provided by 24 bits.
