The TAC5212 is a high-performance stereo audio codec with 2VRMS differential input, 119dB stereo ADC and 2VRMS differential output, 120dB stereo or 1VRMS single-ended output, 111dB quad DAC. The TAC5212 supports both differential and single-ended inputs and outputs. The ADC supports both line/microphone input signals with options for AC or DC coupling configurations. The DAC outputs can be configured for either line-output or headphone loads. The DAC can drive up to 62.5mW into a 16Ω headphone load. The TAC5212 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 and ultra-low latency filter modes, and allows for sample rates up to 768kHz for both ADC and DAC signal chains. The TAC5212 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 an excellent choice for space-constrained audio applications.
