The recommended input voltage range for the REF02AJ/883B is 4V to 36V, although it can operate with inputs as low as 2.5V. However, the output voltage accuracy and temperature coefficient may degrade at lower input voltages.
To ensure stability and accuracy, it's essential to decouple the input pin with a 10uF capacitor, and the output pin with a 10nF capacitor. Additionally, keep the device away from high-current switching nodes and ensure a low-impedance power supply.
The output impedance of the REF02AJ/883B is typically around 0.2 ohms, which is relatively low. This makes it suitable for driving high-impedance loads, such as ADCs or DACs.
The REF02AJ/883B is rated for operation up to 125°C, making it suitable for high-temperature applications. However, the output voltage accuracy and temperature coefficient may degrade at higher temperatures.
To calculate the total error budget, consider the initial accuracy, temperature coefficient, and long-term drift of the REF02AJ/883B. You can use the datasheet specifications to calculate the total error budget, taking into account the operating temperature range and desired accuracy.
