TEXAS INSTRUMENTS TLV320DAC3202EVM 评估模块, TLV320DAC3202EVM
The is a low power high fidelity I2S input headset evaluation module. The TLV320DAC3202 is a CMOS, monolithic, integrated circuit which includes stereo digital to analog converters, headset amplifiers, and power management support circuitry in small 20 pin wafer chip scale packageWCSP. The data converters use enhanced multilevel architecture, which employs noise shaping and multilevel amplitude quantization to achieve excellent dynamic performance and improved tolerance to clock jitter. The device accepts several industry standard audio data formats with 16bit to 24bitit data, left justified, I2S, etc., providing easy interfacing to audio DSP and decoder devices. Sampling rates up to 48KHz are supported. A full set of user programmable functions is accessible through a standardised two wire I2C serial control port, which supports register write functions.
