It is recommended to place the REF5050IDGKR close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is providing a reference voltage to, and to use a star-ground configuration to minimize noise. Additionally, it is recommended to use a low-impedance, low-inductance path for the reference voltage output.
It is recommended to use a 10uF to 22uF ceramic capacitor in parallel with a 100nF to 1uF ceramic capacitor, placed as close as possible to the REF5050IDGKR, to bypass and decouple the device. Additionally, it is recommended to use a low-ESR capacitor to minimize noise and oscillations.
The recommended input voltage range for the REF5050IDGKR is 4.5V to 18V. Operating the device outside of this range may affect the output voltage accuracy, with the device specified to maintain an accuracy of ±0.05% over the recommended input voltage range.
The REF5050IDGKR's output voltage accuracy is affected by temperature, with a typical temperature coefficient of 10ppm/°C. This means that for every 1°C change in temperature, the output voltage may change by 10ppm.
The recommended output capacitor value for the REF5050IDGKR is 10uF to 22uF, with a low-ESR ceramic capacitor recommended. The output capacitor value and type can affect the device's stability, with a larger capacitor value helping to improve stability but also increasing the device's settling time.
