The recommended power-up sequence is to first apply the analog power supply (AVDD) and then the digital power supply (DVDD). This ensures that the analog circuitry is powered up before the digital circuitry.
The TAS5704PAPR can be configured for mono or stereo operation by setting the MONO/STEREO pin high or low, respectively. In mono mode, the left and right channels are summed and output on both channels. In stereo mode, the left and right channels are output separately.
The maximum power that the TAS5704PAPR can deliver to a load depends on the supply voltage and the load impedance. With a 12V supply and a 4Ω load, the maximum power is approximately 10W per channel. However, this can be increased to 20W per channel with a 24V supply and a 2Ω load.
The gain of the TAS5704PAPR can be adjusted by setting the GAIN pin to a specific voltage level. The gain range is from -12dB to +12dB, with 0dB being the default gain setting.
The FLT pin is a fault detection pin that indicates when the device has detected an over-temperature, over-current, or under-voltage condition. When a fault is detected, the FLT pin goes low, and the device enters a shutdown mode to protect itself from damage.
