The TAC5112 is a low power Stereo Codec with 2 VRMS differential Input, 100 dB Stereo ADC and 2 VRMS Stereo DAC. The TAC5112 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. TAC5112 can drive up to 62.5 mW into a Headphone Load. The TAC5112 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 TAC5112 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 TAC5112 an excellent choice for space-constrained audio applications.
