TAS3108IADCP datasheet by Texas Instruments

TAS3108IADCP Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TAS3108IADCP?
  The recommended power-up sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures proper initialization and prevents damage to the device.
• How do I configure the TAS3108IADCP for stereo audio output?
  To configure the TAS3108IADCP for stereo audio output, set the STEREO pin high and connect the left and right channel audio signals to the corresponding pins (LROUT and RROUT). Additionally, ensure that the I2S format is set to 16-bit or 24-bit stereo mode.
• What is the maximum power consumption of the TAS3108IADCP?
  The maximum power consumption of the TAS3108IADCP is approximately 120 mW when operating at 3.3 V and 48 kHz sampling frequency. However, this value can vary depending on the specific application and operating conditions.
• How do I implement a mute function using the TAS3108IADCP?
  To implement a mute function, connect the MUTE pin to a digital output and drive it high to mute the audio output. Alternatively, you can use the I2C interface to set the mute register (0x10) to enable or disable the mute function.
• What is the recommended layout and routing for the TAS3108IADCP?
  To ensure optimal performance and minimize noise, follow these layout and routing guidelines: keep the analog and digital signals separate, use a solid ground plane, and route the clock signal away from the analog signals. Additionally, place decoupling capacitors close to the power pins and use a low-ESR capacitor for the AVDD pin.
