DAC7750IPWP datasheet by Texas Instruments

DAC7750IPWP Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the DAC7750IPWP?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the digital inputs. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate voltage output from the DAC7750IPWP?
  To ensure accurate voltage output, it is essential to use a high-precision voltage reference, such as the Texas Instruments REF5025. Additionally, ensure that the output voltage is buffered with an op-amp, such as the OPA333, to minimize output impedance and improve accuracy.
• What is the maximum output current of the DAC7750IPWP?
  The maximum output current of the DAC7750IPWP is 5 mA. Exceeding this current may cause device damage or affect output accuracy.
• How do I handle the DAC7750IPWP's digital inputs during power-up and power-down?
  During power-up and power-down, it is recommended to keep the digital inputs in a high-impedance state or tie them to a fixed logic level to prevent unwanted device operation.
• What is the recommended layout and routing for the DAC7750IPWP?
  To minimize noise and ensure accurate operation, it is recommended to use a multi-layer PCB with a solid ground plane, keep analog and digital signals separate, and use short, direct traces for the output voltage and reference voltage connections.
