STA381BW Frequently Asked Questions (FAQ)
-
STMicroelectronics provides a recommended PCB layout in the application note AN4841, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and thermal dissipation.
-
The STA381BW can be configured for different audio formats using the I2C interface. The device has several registers that control the audio format, such as the audio clock frequency, bit depth, and channel mode. Refer to the datasheet and application notes for specific configuration details.
-
The maximum power consumption of the STA381BW depends on the operating mode and clock frequency. According to the datasheet, the maximum power consumption is around 250mW in the highest performance mode. However, this can be reduced to around 50mW in low-power modes.
-
The STA381BW has a built-in digital microphone interface that can be connected to a digital microphone. The interface requires a clock signal, data signal, and power supply. Refer to the datasheet and application notes for specific implementation details and recommended component values.
-
The noise floor of the STA381BW is around -90dB, which is typical for audio codecs in this class. However, this can be improved by using proper PCB layout, component selection, and noise reduction techniques.
