AD7547JNZ Parameter Table

Instructions for AD7547JNZ

1. Power Supply:

   • Connect the VDD pin to a stable 5V supply.
   • Ensure that the power supply is clean and has adequate filtering to avoid noise affecting the DAC output.

2. Digital Inputs:

   • The digital inputs (D0-D11) should be driven by a logic level compatible with the VD supply.
   • Ensure that the digital inputs are not left floating; they should be tied to either VD or ground when not in use.

3. Output Configuration:

   • The analog output (VOUT) will range from 0V to VDD based on the digital input code.
   • Use appropriate load resistors and capacitors to filter the output if necessary.

4. Programming the DAC:

   • The AD7547JNZ can be programmed using a parallel interface.
   • Write the 12-bit digital code to the DAC by setting the appropriate logic levels on the D0-D11 pins.
   • Assert the LOAD input to latch the data into the DAC register and update the output.

5. Power-Up Sequence:

   • Apply VDD first, followed by VD.
   • Ensure that the power-up sequence is followed to avoid any potential damage or incorrect operation.

6. Thermal Considerations:

   • The device should be mounted on a PCB with adequate heat dissipation.
   • Avoid operating the device at temperatures exceeding the maximum specified in the parameter table.

7. Storage and Handling:

   • Store the device in a dry environment within the specified storage temperature range.
   • Handle the device with care to avoid static discharge, which can damage the internal circuits.

By following these instructions, you can ensure reliable and optimal performance of the AD7547JNZ DAC in your application.
