Texas Instruments recommends a star-ground connection, placing the REF3325AIDCKTG4 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 or high-frequency signals, and use a ground plane to reduce noise.
The REF3325AIDCKTG4 requires a single 2.7V to 5.5V power supply. Ensure the power supply is stable and well-regulated before applying it 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 REF3325AIDCKTG4 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 REF3325AIDCKTG4 has a temperature coefficient of 10 ppm/°C, which means the output voltage changes by 10 ppm for every 1°C change in temperature. To minimize temperature-related errors, ensure good thermal management by providing adequate heat dissipation, using a thermally conductive PCB material, and keeping the device away from heat sources.
The REF3325AIDCKTG4 is a sensitive device and can be affected by EMI. To minimize EMI, use a shielded enclosure, keep the device away from high-frequency sources, and use a low-pass filter or ferrite bead on the power supply lines. Ensure the system design meets the relevant EMC standards and regulations.
