TLA2021IRUGR Frequently Asked Questions (FAQ)
-
A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between the analog and digital grounds to filter out high-frequency noise.
-
Use a high-impedance input buffer, such as an op-amp, to buffer the input signal. This will prevent loading effects and ensure accurate voltage measurement. Also, use a low-noise, low-impedance voltage reference, such as the TL431, to provide a stable reference voltage.
-
The TLA2021IRUGR can handle input voltages up to 36V, but it's recommended to limit the input voltage to 30V to ensure reliable operation and prevent damage to the device.
-
Calibrate the device by applying a known input voltage and adjusting the offset and gain trim pins to achieve the desired accuracy. Use a high-precision voltage reference and a calibrated multimeter to ensure accurate calibration.
-
Power up the device in the following sequence: VCC, VREF, and then VIN. This ensures that the internal voltage regulators are properly initialized and the device operates correctly.
