The REF02CSA should be placed close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is supplying, and the output capacitor should be placed as close as possible to the REF02CSA output pin. The input and output pins should be routed away from noisy digital signals and power supply lines. A ground plane under the REF02CSA can also help to reduce noise.
To ensure stability, the REF02CSA requires a minimum output capacitance of 10uF, and the output capacitor should be a low-ESR type. The REF02CSA should also be decoupled from the power supply with a 0.1uF capacitor. Additionally, the PCB layout should be designed to minimize parasitic inductance and capacitance.
The maximum allowed voltage on the input pin of the REF02CSA is 12V. Exceeding this voltage can cause damage to the device.
Yes, the REF02CSA can be used in a system with a switching power supply, but it is recommended to add additional filtering to remove high-frequency noise from the power supply. A pi-filter or a ferrite bead can be used to filter out high-frequency noise.
During power-up, the REF02CSA output voltage ramps up slowly to prevent overshoot and ensure a stable output. During power-down, the REF02CSA output voltage decays slowly to prevent undershoot and ensure a stable output.
