AD1938YSTZ Overview
Space-saving is achieved by supplying it in the 48-LQFP package. As a packaging method, Tray is adopted. The high-efficiency performance of this electronic part can be achieved in various applications due to its type of General Purpose. Mounting type Surface Mount is used. At -40°C~105°C, it can operate normally. It consists of 4 / 8 ADCs/ DACs. The analog circuit is powered by 3V~3.6V. Digital circuits are powered by 3V~3.6V supply voltages. To prevent signals from reflecting off of the transmission line, there are 48 terminations. The device has 48 pins. The pins are configured as 48. Its base part number AD1938 can be used to find other parts that are related. Surface Mount technology is used for mounting it to a PCB. It is recommended to maintain the maximum supply voltage at 3.6V. Converting analog signals to digital signals requires 4 A/D converters. Supply voltage should be maintained at 3V. Voltage 3.3V is used for its power supply. 3.3V is the supply voltage that it can operate from. For the conversion of digital signals into analog ones, 8 D/A converters are used. To store information, there are 24 bits available. An external factor does not affect the amount of 56mA current consumed.
