DAC8164IBPW datasheet by Texas Instruments

DAC8164IBPW Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8164?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital supply (DVCC). This ensures that the analog and digital sections of the device are powered up correctly.
• How do I ensure accurate voltage output from the DAC8164?
  To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the REF5025 or REF5030, and to follow proper PCB layout and design guidelines to minimize noise and interference.
• What is the maximum output current of the DAC8164?
  The maximum output current of the DAC8164 is 10 mA per channel. Exceeding this current limit can cause damage to the device or affect its accuracy.
• How do I synchronize multiple DAC8164 devices?
  To synchronize multiple DAC8164 devices, use the SYNC pin to synchronize the internal clock of each device. This ensures that the devices update their outputs simultaneously, which is essential in applications requiring coordinated output signals.
• What is the purpose of the CLR pin on the DAC8164?
  The CLR (Clear) pin is used to reset the DAC8164 to its power-on state. When the CLR pin is asserted low, the device resets its internal registers and output voltage to zero, allowing for a controlled startup sequence.
