The TAC5412-Q1 is a high performance Stereo Codec with 10VRMS differential Input, 108dB Stereo ADC and 2VRMS Stereo DAC Channels. The TAC5412-Q1 supports both differential and Single Ended input and output. Device supports both Microphone and Line In input on ADC Channel. DAC Output can be configured for either Line Out or Head Phone Load. TAC5412-Q1 can drive up to 62.5mW into a Headphone Load. The device also offers an integrated high-voltage, programmable microphone bias, and input diagnostic circuitry that allows direct connection to microphone-based automotive systems with full fault diagnostic capability for direct-coupled inputs. The TAC5412-Q1 integrates an efficient boost converter to generate a high voltage microphone bias using an external, low-voltage, 3.3V supply, The device can also directly use an external high-voltage supply (HVDD), which is a readily available supply in the system to generate the high-voltage, programmable microphone bias. The TAC5412-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. It allows for sample rates up to 768kHz. The TAC5412-Q1 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with I2C. These integrated high-performance features, along with a single, 3.3V supply operation, makes TAC5412-Q1 an excellent choice for space-constrained automotive systems.
