STEVAL-CCA018V1演示板旨在提供一个平台，用于评估TS4657立体声数字模拟转换器（DAC）的性能。该TS4657集成了能产生从一个单一的3.0至5.5 V电源供电2.2 Vrms输出级的高性能音频线路驱动器。The STEVAL-CCA018V1 demonstration board is designed provide a platform for evaluating the performance of the TS4657 stereo digital-to analog-converter (DAC). The TS4657 integrates a high-performance audio line driver capable of generating a 2.2 VRMS output level from a single 3.0 to 5.5 V supply.A single supply is sufficient for the digital and analog parts of the circuit, eliminating the need for external regulators.The TS4657 is a low consumption device, with only 22 mW of power dissipation at 3.0 V power supply during full operation.A 16-bit multi-bit sigma-delta DAC is used, operating at 256xFs with over sampling digital interpolation filters.The digital audio data can be 16 to 24-bits long and sample rates from 32 to 48 kHz are supported.The output stage signal is ground-referenced by using an internal self-generated negative power supply, so bulky external output coupling capacitors are not necessary.
