Frequently Asked Questions
Why choose 4.096V as a reference voltage?
4.096V is exactly 4096mV, which provides convenient binary scaling: with a 12-bit ADC (4096 counts), each LSB equals exactly 1mV. This simplifies firmware calculations and eliminates floating-point math for voltage conversion.
What is the accuracy of LM4030C grade?
The LM4030C (C grade) provides ±0.05% initial accuracy at 25°C, meaning the output is 4.096V ±2mV. Combined with 20ppm/°C temperature coefficient, total error over -40°C to 85°C range is well within 12-bit system requirements.
How do you bias the LM4030 shunt reference?
Connect a resistor from the positive supply to the cathode, and connect the anode to ground. Operating current range is 100µA to 15mA. Calculate the bias resistor as R = (Vsupply - 4.096V) / (Iload + Ibias), where Ibias should be at least 100µA.
What noise performance does LM4030 offer?
The LM4030 achieves 10µVpp noise in the 0.1Hz to 10Hz band, suitable for 16-bit system requirements. For even lower noise, add a 0.1µF bypass capacitor at the output. Broadband noise is 25µVRMS over 10Hz to 10kHz.
