AK4637EN Overview
Due to space constraints, it is supplied in the 20-WFQFN Exposed Pad package. This package uses the Cut Tape (CT) packaging method. This electronic part is categorized as a type of 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 1 / 1 ADCs and DACs. The analog circuit receives 2.8V~3.5V as a supply voltage. It receives a voltage of 1.6V~1.98V as its supply voltage. Based on the Surface Mount technology, the module is mounted to a PCB. 85°C is set as the maximum operating temperature to keep the system working normally. Normal operation is maintained by setting the operating temperature low at -40°C.
