To determine the power requirements for the ANALOG DEVICES Precision High Voltage Density Optimized Voltage Drive, you need to refer to the "POWER REQUIREMENTS" section in the user guide. This section provides information on the supply voltage, supply current, and power supply rejection ratio (PSRR) for different stages of the device.
The power requirements are divided into two stages: DAC & DRIVER and ISOLATOR. For each stage, the user guide provides the part numbers of the specific components used.
For the DAC & DRIVER stage, the supply voltage is specified for different pins, including V+, AVCC, VLOGIC/DVCC, VPP/VDD, VDD1, and VDD2. The supply current is also provided for each pin. Additionally, the PSRR is mentioned.
For the ISOLATOR stage, the supply voltage and supply current are specified for the ADuM1441 isolator.
It is important to note that the supply currents indicated are the maximum quiescent current of the supply rails, and for overall full load or short circuit current specifications, you should refer to the datasheets of the signal chain components. The supply voltages indicated are typical values for typical applications.
If you need more specific details on power dissipation or if you have a specific number of channels on the signal chain, it is recommended to consult the corresponding datasheets for further information.
Please refer to the user guide for the ANALOG DEVICES Precision High Voltage Density Optimized Voltage Drive for more comprehensive information and details on power requirements.
