REF02BP Frequently Asked Questions (FAQs)
The REF02BP should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is referencing, with a low-impedance path to the power supply. The input and output pins should be routed away from noisy digital signals, and a ground plane should be used to minimize noise coupling.
A 0.1 μF ceramic capacitor should be placed as close as possible to the REF02BP's input pin, and a 10 μF tantalum capacitor should be placed in parallel to filter out high-frequency noise. Additionally, a 1 μF ceramic capacitor can be placed on the output pin to filter out high-frequency noise.
The REF02BP's output voltage has a temperature coefficient of 10 ppm/°C. To compensate for temperature effects, a temperature sensor can be used to monitor the temperature and adjust the reference voltage accordingly. Alternatively, a thermistor can be used to create a temperature-compensated voltage reference.
The REF02BP requires a power supply voltage between 4.5 V and 36 V, with a recommended operating voltage of 5 V or 15 V. The power supply should be well-regulated and have a low noise floor to ensure accurate voltage reference. A voltage regulator, such as the TLV703, can be used to regulate the power supply voltage.
The REF02BP should be powered up and down slowly to prevent damage from inrush currents. A soft-start circuit can be used to limit the inrush current during power-up. Additionally, the input voltage should be ramped up and down slowly to prevent voltage spikes.
