The REF6250IDGKT is a sensitive device and requires careful layout and placement to ensure optimal performance. TI recommends placing the device close to the analog-to-digital converter (ADC) or digital-to-analog converter (DAC) it is driving, and using a solid ground plane to minimize noise. Additionally, the device should be decoupled with a 0.1uF capacitor to reduce noise and oscillations.
To ensure stability, the REF6250IDGKT requires a minimum load capacitance of 10nF and a maximum load capacitance of 100nF. Additionally, the device should be decoupled with a 0.1uF capacitor and placed close to the ADC or DAC it is driving. It is also recommended to use a low-ESR capacitor and to avoid using long traces or wires that can introduce noise and oscillations.
The typical start-up time for the REF6250IDGKT is around 10ms, but this can vary depending on the specific application and operating conditions. It is recommended to wait for at least 10ms after power-up before using the reference voltage to ensure that it has stabilized.
The REF6250IDGKT is rated for operation up to 125°C, but its performance may degrade at high temperatures. It is recommended to derate the device's performance at high temperatures and to ensure that the device is properly heat-sinked to prevent overheating.
The total error budget for the REF6250IDGKT includes the initial accuracy, temperature coefficient, and long-term drift. The initial accuracy is typically ±0.02% at 25°C, the temperature coefficient is ±10ppm/°C, and the long-term drift is ±50ppm/1000 hours. The total error budget can be calculated by summing these errors and considering other sources of error in the system.
