The TAC5142 is a stereo audio codec with 2VRMS differential input, 103dB dynamic range ADC and 2VRMS differential output, 110dB dynamic range DAC. The TAC5142 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 and the DAC output can be configured for either line-output or headphone loads. The DAC can drive upto 62.5mW into a 16Ω headphone load. The device integrates a phase-locked loop (PLL) and supports sample rates up to 192kHz for both the ADC and DAC signal chains. The device also integrates a DC-removal digital high-pass filter (HPF) with configurable cut-off for the ADC signal chain. The TAC5142 supports time-division multiplexing (TDM), left-justified (LJ), or I2S audio formats in controller and target modes, and is pin or hardware controlled. These integrated high-performance features, pin control along with a single supply operation, make TAC5142 an excellent choice for space-constrained audio applications.
