TAA5412-Q1 Stereo Audio ADC

Texas Instruments TAA5412-Q1 Stereo Audio Analog-to-Digital Converter (ADC) is a 2-channel high-performance audio ADC that supports analog input signals up to 10V_RMS with a dynamic range of 112dB. The TAA5412-Q1 allows for single-ended and differential input configurations and supports line and microphone inputs with AC and DC coupling options. This device offers programmable microphone bias, an integrated high-voltage, and input diagnostic circuitry directly connecting microphone-based automotive systems with full fault diagnostic capability for direct-coupled inputs. The TAA5412-Q1 uses an external, low-voltage, 3.3V supply to integrate an efficient boost converter to generate a high-voltage microphone bias. The device can create this microphone bias by using an external high-voltage supply (HVDD), which is any readily available supply in the system.
