The recommended power-up sequence is to power up the digital supply (DVDD) first, followed by the analog supply (AVDD). This ensures that the digital circuitry is powered up before the analog circuitry to prevent any unwanted analog signals from being generated.
The TLV320AIC1103PBSR can be configured for master or slave mode by setting the appropriate values on the BCLK, LRC, and MCLK pins. In master mode, the codec generates the clock signals, while in slave mode, it receives clock signals from an external source. The specific configuration depends on the application and system requirements.
The maximum input signal level that the TLV320AIC1103PBSR can handle is 2.2 Vrms for the analog-to-digital converter (ADC) and 1.5 Vrms for the digital-to-analog converter (DAC). Exceeding these levels may result in signal distortion or clipping.
To optimize the TLV320AIC1103PBSR for low power consumption, use the power-down modes, reduce the clock frequency, and adjust the analog and digital supply voltages to the minimum required levels. Additionally, consider using the codec's built-in power-saving features, such as the automatic power-down mode.
The recommended layout and routing for the TLV320AIC1103PBSR involves separating the analog and digital signal paths, using ground planes to reduce noise, and minimizing the length of the clock signal traces. Additionally, ensure that the power supply decoupling capacitors are placed close to the codec's power pins.
