The recommended power-up sequence is to apply VCC first, followed by VREF, and then the digital inputs. This ensures proper device operation and prevents potential latch-up conditions.
To ensure accurate voltage output, it is essential to use a stable and low-noise voltage reference (VREF) and to decouple the VREF pin with a capacitor to reduce noise. Additionally, ensure that the output load is within the specified range to prevent output voltage droop.
The maximum output current capability of the DAC5571IDBVR is 5 mA. Exceeding this limit may cause device damage or affect output accuracy.
During power-up and power-down, it is recommended to keep the digital inputs (SCL and SDA) in a high-impedance state or tied to a fixed logic level to prevent unwanted device operation or latch-up conditions.
To minimize noise and ensure accurate operation, it is recommended to keep the analog and digital signal paths separate, use a solid ground plane, and minimize trace lengths and loops. Additionally, place decoupling capacitors close to the device pins.
