PCM3794ARHBR Overview
Due to space constraints, it is supplied in the 32-VFQFN Exposed Pad package. This package uses the Tape & Reel (TR) packaging method. This electronic part is categorized as a type of Stereo Audio, making it capable of providing high-efficiency performance in a variety of applications. Surface Mount is the mounting type employed by this device. Operating performance -40°C~85°C permits it to function normally. In addition, it is equipped with 2 / 2 ADCs and DACs. The analog circuit receives 2.4V~3.6V as a supply voltage. It receives a voltage of 1.71V~3.6V as its supply voltage. In order to prevent signal reflections from off the end of the transmission line, 32 terminations are used. Essentially, it is an electronic device with 32 pins. There are 32 pins on this board. Using its base part number PCM3794, it can be used to locate parts that are related. 3.6V is the maximum value of supply voltage. Analog signals are converted to digital signals by means of 2 A/D converters. Minimum supply voltage should remain at 1.71V. There is 3.3V supply voltage for this device. It can be operated from a voltage of 3.3V. For data transmission, the device has 4 channels. A total of 16 bits are provided for storing information. It is expected that 10μA will flow normally through the circuit throughout its lifetime.
