DAC2932PFBR datasheet by Texas Instruments

DAC2932PFBR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC2932?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures that the internal voltage regulators are powered up correctly and the device operates reliably.
• How do I ensure accurate voltage output from the DAC2932?
  To ensure accurate voltage output, it is essential to use a high-quality external voltage reference, such as the REF5025 or REF5030, and to follow proper PCB layout and decoupling techniques to minimize noise and interference.
• What is the maximum output current of the DAC2932?
  The maximum output current of the DAC2932 is 10 mA per channel. Exceeding this current limit can cause damage to the device or affect its accuracy.
• Can I use the DAC2932 with a single supply voltage?
  Yes, the DAC2932 can operate with a single supply voltage, but it requires an external voltage regulator to generate the required internal voltages. TI provides a reference design for single-supply operation in the datasheet.
• How do I synchronize the DAC outputs in a multi-channel application?
  The DAC2932 has a SYNC pin that allows synchronization of the DAC outputs. By connecting the SYNC pins of multiple devices together and applying a common SYNC signal, the DAC outputs can be synchronized to ensure simultaneous updates.
