REF3450SQDBVRQ1 Frequently Asked Questions (FAQ)
-
A good PCB layout for the REF3450SQDBVRQ1 involves keeping the input and output pins as close as possible to minimize noise and parasitic inductance. Additionally, use a solid ground plane and decouple the input with a 10uF capacitor to reduce noise and ripple.
-
To ensure accurate voltage output over temperature, it's essential to consider the temperature coefficient (TC) of the REF3450SQDBVRQ1. The TC is specified as 2ppm/°C. You can use external components, such as thermistors or thermocouples, to compensate for temperature variations and maintain accurate output.
-
The recommended input voltage range for the REF3450SQDBVRQ1 is between 4.5V and 18V. Operating outside this range may affect the device's accuracy, stability, and long-term reliability.
-
To protect the REF3450SQDBVRQ1 from power-on surges and ESD, use a voltage clamp, such as a TVS diode, on the input pin. Additionally, consider adding a series resistor and a capacitor to filter out high-frequency noise and transients.
-
The recommended output capacitor value for stability is 10uF to 22uF. This helps to filter out high-frequency noise and ensure stable output voltage. However, the optimal value may vary depending on the specific application and PCB layout.
