REF191ESZ-REEL Frequently Asked Questions (FAQ)
-
A good PCB layout for the REF191ESZ-REEL involves keeping the input and output traces short and away from noise sources, using a solid ground plane, and decoupling the device with a 10uF capacitor.
-
To ensure stability, ensure that the output capacitor is properly sized and placed close to the device, and that the input voltage is within the recommended range. Also, avoid using long output traces and minimize the distance between the device and the output capacitor.
-
The maximum allowed power dissipation for the REF191ESZ-REEL is 500mW. Exceeding this limit can cause the device to overheat and potentially fail.
-
The REF191ESZ-REEL 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 at high temperatures and consider using a thermally-enhanced package or a different device if high-temperature operation is required.
-
To minimize noise sensitivity, use a low-noise power supply, decouple the device with a 10uF capacitor, and keep the input and output traces short and away from noise sources. Additionally, consider using a noise-reducing capacitor on the output.
