DAC8234SPFB datasheet by Texas Instruments

DAC8234SPFB Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC8234SPFB?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then DVCC. This ensures that the internal voltage regulators are powered up correctly.
• How do I ensure accurate voltage output from the DAC?
  To ensure accurate voltage output, it is recommended to use a high-precision voltage reference, such as the Texas Instruments REF5025. Additionally, the DAC output should be filtered using a low-pass filter to remove any noise and glitches.
• What is the maximum output current of the DAC8234SPFB?
  The maximum output current of the DAC8234SPFB is 5mA per channel. Exceeding this current limit may cause damage to the device or affect its accuracy.
• How do I synchronize multiple DAC8234SPFB devices?
  To synchronize multiple DAC8234SPFB devices, connect the SYNC pin of each device together and drive it with a common clock signal. This ensures that all devices update their outputs simultaneously.
• What is the purpose of the LDAC pin?
  The LDAC (Load DAC) pin is used to update the DAC output. When LDAC is low, the DAC output is updated with the new data. When LDAC is high, the DAC output is latched and does not change.
