描述 Description

The TAD5212-Q1 is a high performance Stereo 2VRMS DAC. The TAD5212-Q1 supports both differential and Single Ended input and output. DAC Output can be configured for either Line Out or Head Phone Load. TAD5212-Q1 can drive upto TBD mW into a Headphone Load. The TAD5212-Q1 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-Q1 supports Analog Input to Output Bypass option. Data from Analog-In and Digital-In can be mixed inside the device as well. The TAD5212-Q1 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-Q1 an excellent choice for space-constrained audio applications.
