[Domestic Audio Compilation Decoder] Cjc8988pin-To-Pin Replace WM8988

CJC8988 chip is an AD/DA converter with two headphones amplifiers or stereo input and output interfaces with ultra -low -power dual -road ADC and DAC audio encoders.And programmable volume adjustment capabilities.

Support multiple audio data interfaces, including I2S, 24bit/20bit/16bit, LEFT RIGHT Justified and other formats. At the same time, powerful functions such as volume control, mute, aggravation, power management, 3D enhancement and other powerful functions.There are also advanced filmsDigital signal processingFunction, executable graphics balancer, three -dimensional sound enhancement and automatic level control to make the audio input clearer and three -dimensional.

CJC8988 can work normally when the power supply voltage drops to 1.8V. The core core can even run at a voltage of 1.5V to save energy. The maximum power supply voltage is 3.3V.In addition, each part of the chip can be disconnected under software control, providing 4X4MMCol packaging, which is extremely compact and suitable for handheld and portable systems.
