Texas Instruments recommends a star-ground configuration and a solid ground plane to minimize noise and ensure optimal performance. Additionally, keep the input and output traces short and separate to reduce noise coupling.
To ensure stability, make sure to decouple the input and output pins with suitable capacitors (e.g., 10nF to 100nF) and use a low-ESR capacitor (e.g., X5R or X7R) for the output capacitor. Also, avoid using long traces and keep the layout compact.
The maximum allowed input voltage for the REF3233AIDBVR is 18V. Exceeding this voltage may damage the device. It's recommended to use a voltage regulator or a voltage limiter to ensure the input voltage stays within the specified range.
The REF3233AIDBVR is rated for operation up to 125°C. However, the device's accuracy and stability may degrade at high temperatures. It's recommended to derate the device's performance and consider using a thermally-enhanced package or a heat sink to maintain optimal performance.
The output noise of the REF3233AIDBVR can be calculated using the formula: Noise (rms) = √(Vn^2 + (I_n * R_l)^2), where Vn is the input noise, I_n is the input current noise, and R_l is the load resistance. Refer to the datasheet for the specific noise values and calculation details.
