The recommended power-up sequence is to first apply the analog power supply (VDDA) and then the digital power supply (VDDD). This ensures that the analog circuitry is powered up before the digital circuitry.
To optimize the UDA1341TS for low power consumption, use the power-down mode (PD pin) to shut down the device when not in use. Additionally, adjust the clock frequency and analog gain to the minimum required for the application.
The maximum clock frequency that can be used with the UDA1341TS is 50 MHz. However, the recommended clock frequency is 12.288 MHz for optimal performance.
To configure the UDA1341TS for stereo audio applications, connect the left and right audio channels to the corresponding inputs (AINL and AINR) and use the stereo mode (ST pin) to enable stereo operation.
The recommended layout and routing for the UDA1341TS involves separating the analog and digital power supplies, using a ground plane, and keeping the analog and digital signal traces separate to minimize noise and interference.
