Description for the TAC5312-Q1
The TAC5312-Q1 is a low-power stereo audio codec with 10VRMS differential input, 104dB ADC and 2VRMS differential output, 114dB DAC. The TAC5312-Q1 supports both differential and single-ended inputs and outputs. The device supports both microphone and line inputs on the ADC channels with options for AC and DC coupling configurations. The DAC outputs can be configured for either line-out or headphone loads. TAC5312-Q1 can drive up to 62.5mW into a 16Ω 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 complete fault diagnostic capability for direct-coupled inputs. The TAC5312-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 any readily available supply in the system to generate this microphone bias. The TAC5312-Q1 integrates a programmable channel gain, digital volume control, a low-jitter phase-locked loop (PLL), a programmable high-pass filter (HPF), programmable EQ and biquad filters, and interpolation and decimation filters with low and ultra-low latency filter modes. The device allows for sample rates up to 768kHz. The TAC5312-Q1 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, 3.3V supply operation, make TAC5312-Q1 an excellent choice for space-constrained automotive systems.
