Data Output Pin Of Serial Port 1 The serial data is clocked out through this pin
MAX1473EUI 特点
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, JA, and the ambient temperature, TA. The maximum allowable power dissipation is PDMAX = (TJMAX − TA) / JA or the given in Absolute Maximum Ratings, whichever is lower. For the MAX1473EUI typical application (shown in Figure 1) with VDD = 12V, RL = 4Ω stereo operation the total power dissipation is 3.65W. JA = 35˚C/W.
MAX1473EUI 应用
WRITE Write operations are initiated by taking CS LOW and clocking in a start bit followed by the write command and the address of the data register to be written. This action is followed by the host clocking eight bits of data into the register, MSB first. The output of the selected DAC will change as the last bit is clocked into the device. At this point the clock counter will reset the command register, requiring a full sequence to be initiated in order to write to the DAC again. NOTE: This write operation does not affect the contents of the nonvolatile register. Therefore, the nonvolatile register can contain the power-on default settings (e.g. volume), and the write DAC command can be used to make situational adjustments. Refer to Figure 2 for an illustration of the sequence of bus conditions for a write operation.
