Texas Instruments recommends a star-ground connection, with the REF3425QDGKRQ1 placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC), and using a low-impedance power supply. Additionally, keep the device away from high-current switching nodes and use a solid ground plane to reduce noise.
The REF3425QDGKRQ1 requires a single 2.7V to 5.5V power supply. Ensure the power supply is stable and well-regulated before applying power to the device. There are no specific power-up sequencing requirements, but it's recommended to power up the device after the power supply has stabilized.
The typical output impedance of the REF3425QDGKRQ1 is around 0.2 ohms. This low output impedance ensures a stable voltage reference, but it's essential to consider the output impedance when designing the system, especially when driving high-impedance loads or long cables.
The REF3425QDGKRQ1 has a temperature coefficient of 10 ppm/°C, which means it can handle temperature changes relatively well. However, it's still essential to consider thermal management in the system design, such as providing adequate heat sinking and airflow, to ensure the device operates within its specified temperature range.
The REF3425QDGKRQ1 is a relatively low-noise device, but it's still important to consider EMI and RFI in the system design. Use proper shielding, grounding, and decoupling techniques to minimize electromagnetic interference and radio-frequency interference.
