TAD5212中文资料具有 120-dB 动态范围的低功耗立体声音频 DAC数据手册TI规格书

描述 Description

The TAD5212 is a high performanceStereo 2VRMS DAC. The TAD5212 supports both differential and Single Ended input and output. DAC Output can be configured for either Line Out or Head Phone Load. TAD5212 can drive upto TBD mW into a Headphone Load. The TAD5212 integrates programable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), a programmable high-pass filter (HPF), programmable EQ and biquad filters, low-latency filter modes, and allows for sample rates up to 768 kHz. The TAD5212 supports Analog Input to Output Bypass option. Data from Analog-In and Digital-In can be mixed inside the device as well. The TAD5212 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with I2C or SPI. These integrated high-performance features, along with a single supply operation, make TAD5212 an excellent choice for space-constrained audio applications.
