The TAA5412-Q1 is a 2-channel high-performance, audio analog-to-digital converter (ADC) that supports analog input signals up to 10VRMS. The TAA5412-Q1 supports line and microphone inputs, and allows for both single-ended and differential input configurations. This device 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 TAA5412-Q1 integrates an efficient boost converter to generate a high voltage microphone bias using an external, low-voltage, 3.3V supply, which is a readily available supply in the system to generate the high-voltage, programmable microphone bias. The TAA5412-Q1 integrates the programable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), a programmable high-pass filter (HPF), biquad filters, low-latency filter modes, and allows for sample rates up to 768kHz. The TAA5412-Q1 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) audio formats, and can be controlled with either the I2C or SPI interface. These integrated high-performance features, along with a single, 3.3V supply operation, make the TAA5412-Q1 device along with TAC5xxx-Q1 device family an excellent choice for scalable, space-constrained automotive systems. The TAA5412-Q1 is part of a larger TAC5412-Q1 device family, available for download at ti.com.
