KT0210 is a USB audio codec single-chip that provides processing USB audio signals.
KT0210 integrates many interfaces including the stereo analog output, mono analog microphone input, low-noise microphone amplifier, low-noise microphone bias circuit, Class-G audio power amplifier, audio digital signal processor, clock oscillator, DC/DC,LDO, USB interface, 2-wire interface, etc.
KT0210 integrates a USB 2.0 function controller and transceiver, it is compatible with full-speed mode, USB HID device class 1.11 and Audio device class 1.0. It can support all major commercial operating systems (such as Windows, Linux and Android) without drivers.
KT0210 integrate with an audio digital signal processor (DSP), which can realize the audio processing functions such as audio equalizer (EQ), wind-noise filter (WF), noise gate (NG), audio dynamic range compression (DRC), etc. It can realize the various audio processing configurations via FLASH.
KT0210 integrates low-noise microphone pre-amplifier and low-noise microphone bias circuit integration. It integrates headset/headphone plug/unplug detection functions. It supports microphone detection functions. The headset-type of OMTP and CTIA can be automatically identified and configured. High-performance Class-G audio power amplifier can directly drive a 16ohm load without AC coupling capacitor. There is no POP noise while chip powered on or off. It can support up to four configurable key inputs.
KT0210 has internal oscillator and no external crystal is required. 7 GPIOs are available for customers. It has the 2-wire interface, PWM output (breathing light), auxiliary ADC input, external interrupt, etc.
KT0210 can meet the needs of various USB headset/headphone products. It has powerful performance and rich features. The total solution which greatly reduce the difficulty and cost of the development. It also improves the reliability and consistency of products, which making products easier to produce.
