TAC5212-Q1中文资料具有动态范围 115dB ADC 和 120dB DAC 的汽车级低功耗、立体声音频编解码器数据手册TI规格书

描述 Description

The TAC5212-Q1 is a high performance Stereo Codec with 2VRMS differential Input, 118dB Stereo ADC and 2VRMS Stereo DAC. The TAC5212-Q1 supports both differential and Single-ended input and output. The device supports both Microphone and Line In input on the ADC Channel. DAC Output can be configured for either Line Out or Head Phone Load. TAC5212-Q1 can drive up to 62.5mW into a Headphone Load. The TAC5212-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 768kHz. The TAC5212-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, makes TAC5212-Q1 an excellent choice for space-constrained audio applications.
