Audio Special Purpose: STV8206 Application Field and Working Principle

STV8206 is a versatile CMOS integrated circuit designed for high-end audio applications. The device integrates high-performance earphone driver, multiple analog inputs and digital audio interface in one chip. It supports low-power modes and extends battery life. This product is widely used in mobile phones, portable media players and car audio systems.

STV8206 is powered by 3.3V power supply. It is manufactured using 0.18um CMOS process technology, with a low power consumption of only 0.45mW. The device is capable of outputting audio power up to 100mW (max) and delivering a SNR of up to 99dB. The built-in integrated output amplifier in the device makes it ideal for driving high-impedance earphones, headsets, and speakers. It also has low THD+N performance, with a THD+N of 0.05% at 3V output.

The STV8206 integrates four analog inputs and one line input. The four analog inputs are designed for a balanced stereo input paths. They are equipped with automatic gain control (AGC) circuit, and an integrated variable gain amplifier (VGA). The line input is connected to mono signals and its gain can be adjusted via software. In addition, the product enables digital modes for data bit rate up to 48Kbits/second.

The STV8206 includes five control inputs: MUTE, I2C select, line-in selection, digital audio interface enable and digital audio interface control. These control inputs enable users to manage the device’s features. The product also offers several features including headphone detect, device zero-cross detect, variable gain amplifier (VGA) and low-power standby mode.

The working principle of the STV8206 is based on its built-in circuits and components. The device consists of several building blocks, including an analog preamplifier, an analog-to-digital converter (ADC), a digital filter and a digital-to-analog converter (DAC). The pre-amplifier amplifies the input signals from the analog inputs and line inputs. The ADC converts the analog signals into digital ones. The digital filter processes the digital data, while the DAC converts the digital data back into analog signals. The output amplifier amplifies the analog output signal and drives the connected earphones, speakers or other related audio devices.

The STV8206 audio interface is extremely efficient, allowing it to accurately and reliably reproduce high-quality digital audio signal. Its low-power consumption and wide operating voltage range make it an ideal solution for mobile applications. Furthermore, its integrated features provide users with the flexibility to customize their system designs. This product is therefore well-suited for high-end audio applications such as portable audio devices, automotive audio systems and home theater systems.
