S Three-Dimensional Low-Power Multi-Road Direct Sound Collection Encoder-CJC6808

ADC chip -CJC6808 is a low -power audio codec designed for portable audio products.Use QFN48 packaging; its characteristics, performance and low power consumption make it an ideal music player and music signal recipient.Its working voltage mode is 3.0V ～ 3.6V 1.7V ～ 3.6V.Support the length of the digital audio input length from the 16-32-bit digital audio and the sampling rate from 8kHz to 96kHz.The level output of the line also provides anti -heavy strike mute and power supply/decreaseCircuit。

The codec includes 6 lines and microphone inputs, from the line output of the vehicle DAC, a crystal oscillator, a configurable digital audio interface and a 2 -line or 3 -line MPU control interface selection.It is completely compatible and is a series of industry standardsmicroprocessor、ControllerAnd DSP's ideal partner.

CJC6808 includes 6 ADCs and 2 DACs and mute functions, programmable line electrical flat volume control and bias voltage output suitable for electronic microphones; three -dimensional sound 24 -bit Sigma incremental ADC and DAC are used for sampling digital interpolations and extraction extraction and extraction.filter.

CJC6808 also includes a PLL, which can produce a clock of 11.2896MHz.This only requires a crystal of 12.288 MHz, and the crystal does not need to be replaced.When the music sounds, a SAR ADC will be put in to wake up the chip.The device is controlled through the 2 -line or 3 -line serial interface.This interface provides all functions, including volume control, mute, and emphasizing and extensive power management facilities.

ESD sensitive device.The device is made of CMOS process.Therefore, it is usually vulnerable to excessive static voltage damage.When processing and storing the device, appropriate ESD prevention measures must be taken.
