Automotive mono audio codec with 101dB ADC, 110dB DAC and programmable high-voltage mic bias

The TAC5301-Q1 is an automotive, low-power mono audio codec with 2VRMS differential input, 100dB dynamic range ADC and a DAC with 2VRMS differential output, 110dB dynamic range mono channel or 1VRMS single-ended output, 107dB dynamic range stereo channels. The TAC5301-Q1 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. Further, the device has the capability to directly use an external high-voltage supply (HVDD), which is any readily available supply in the system to generate a high-voltage, programmable microphone bias. The TAC5301-Q1 integrates programmable 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 supports sample rates up to 192kHz for both the ADC and DAC signal chains. The TAC5301-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, make TAC5301-Q1 an excellent choice for space-constrained automotive systems.
