DAC8168IAPW datasheet by Texas Instruments

DAC8168IAPW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8168IAPW?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the analog and digital circuits power up in a controlled manner.
• How do I ensure accurate voltage output from the DAC8168IAPW?
  To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the REF5025, and to follow proper PCB layout and grounding techniques to minimize noise and interference.
• What is the maximum output current of the DAC8168IAPW?
  The maximum output current of the DAC8168IAPW is 10 mA per channel. Exceeding this current limit can cause damage to the device.
• How do I synchronize multiple DAC8168IAPW devices?
  To synchronize multiple DAC8168IAPW devices, connect the SYNC pin of each device to a common clock signal. This ensures that all devices update their outputs simultaneously.
• What is the purpose of the LDAC pin on the DAC8168IAPW?
  The LDAC (Load DAC) pin is an asynchronous input that, when low, loads the DAC register with new data. When LDAC is high, the DAC output is updated with the new data.
