The TAA5242 is a high-performance stereo audio ADC with 2VRMS differential input and 119dB dynamic range. The TAA5242 supports both differential and single-ended line/microphone input signals with options for AC or DC coupling configurations. The TAA5242 integrates a low-jitter phase-locked loop (PLL), a digital high-pass filter (HPF) with pin-selectable cut-offs, and supports sample rates up to 192kHz. The TAA5242 supports time-division multiplexing (TDM), I2S, or left-justified (LJ) 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 TAA5242 an excellent choice for space-constrained audio applications.
