KT0707

Description

KT0707 provides a single-chip solution for audio signal processing. The chip only needs simple peripheral circuits to easily realize all functions from audio data collection, audio algorithm processing to analog audio output. 
KT0707 integrates oscillator, phase-locked loop(PLL), 8-channel 8-Bits auxiliary ADC, programmable amplifier (PGA), 4-channel 16-Bits audio ADC with simultaneous input, digital signal processing (DSP), simultaneous output the 2-way 20-Bits audio the DAC, the class AB power amplifier (ClassAB). 
The integrated serial digital audio interface can cooperate with the KT065x series of wireless microphone chips to reduce the number of external components and reduce the performance loss caused by digital-to-analog and analog-to-digital conversion. At the same time, it can also be extended to connect to an external high-performance Codec to meet the needs of customers for higher quality audio.
The audio detection function can automatically enter the standby state when there is no audio output. In the standby state, the extremely low-energy audio detection function can wake up the chip and fully reduce the power consumption of the system.
The built-in high-performance DSP of KT0707 is powerful and supports a variety of audio algorithms. It can meet the needs of microphones, mobile phone live sound cards, mini mixers, and various speakers. 
There are 8-General Purpose Input/Output (GPIO) available for customer use. GPIO has 2-wire interface, PWM output (breathing light), auxiliary ADC input and other functions. 
KT0707 can meet the needs of various products such as microphones, mobile phone live sound cards, mini mixers, and various speakers. The powerful performance and rich functions greatly reduce the development difficulty and cost of the overall solution. The improvement of product reliability and consistency makes production easier.
