REF43GS Frequently Asked Questions (FAQ)
-
The REF43GS is a sensitive device and requires careful layout and placement to minimize noise and ensure optimal performance. It is recommended to place the REF43GS close to the ADC, use a solid ground plane, and keep the input and output traces short and separate from each other and from other noisy signals.
-
The REF43GS has a built-in thermal regulation circuit that helps to maintain a stable output voltage over temperature. However, it is still important to ensure good thermal conductivity between the device and the PCB, and to avoid exposing the device to extreme temperatures or thermal gradients.
-
A 10nF to 100nF ceramic capacitor is recommended to be placed as close as possible to the VIN pin of the REF43GS to filter out high-frequency noise and ensure stable operation.
-
Yes, the REF43GS can be used as a voltage reference for multiple ADCs, but it is recommended to buffer the output of the REF43GS using an op-amp or a buffer amplifier to ensure that the output impedance is low enough to drive multiple loads.
-
The REF43GS requires a power-up sequence to ensure proper initialization. It is recommended to power up the device with a slow ramp-up of the input voltage (typically 1ms to 10ms) to ensure that the internal circuitry is properly initialized.
