The recommended power-up sequence is to power up the analog supply (AVDD) first, followed by the digital supply (DVDD), and then the clock signal. This ensures that the analog circuitry is stable before the digital circuitry is enabled.
The TLV320AIC23BGQE can be configured for master or slave mode by setting the appropriate values on the BCLK, LCLK, and WCLK 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 TLV320AIC23BGQE 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 can result in signal distortion or clipping.
To optimize the TLV320AIC23BGQE for low power consumption, use the power-down modes, reduce the clock frequency, and adjust the analog and digital supply voltages. Additionally, consider using the codec's built-in power-saving features, such as the automatic power-down mode, which can reduce power consumption when the codec is not in use.
The recommended layout and routing for the TLV320AIC23BGQE involves separating the analog and digital signal paths, using a solid ground plane, and minimizing the length of the clock signal traces. Additionally, it is recommended to use a 4-layer PCB with a dedicated analog ground plane and to follow the guidelines provided in the datasheet for component placement and routing.
