Frequently Asked Questions
What output accuracy and temperature coefficient does LM4050BEM3-2.0 offer for precision circuits?
LM4050BEM3-2.0 provides a 2.048 V shunt reference with ±0.2% initial accuracy and a temperature coefficient of 50 ppm/°C, maintaining stable output voltage over the -40°C to 125°C industrial temperature range for precision ADC and calibration applications.
How does the two-terminal shunt topology of LM4050BEM3-2.0 simplify PCB design?
As a shunt reference, LM4050BEM3-2.0 requires only a single current-setting resistor connected between the supply and the reference pin, reducing component count versus a three-terminal series reference. This simple 2-component circuit in a 3-pin SOT-23 package is straightforward to place near ADC VREF pins on space-constrained boards.
Which 12-bit ADC reference circuits benefit from using LM4050BEM3-2.0 at 2.048 V?
12-bit ADCs with a 2.048 V full-scale range achieve 0.5 mV per LSB resolution when referenced to LM4050BEM3-2.0, making it ideal for temperature sensors, pressure transducers, and current measurement systems where high accuracy at the reference node is essential. Industrial PLCs and data loggers commonly pair this reference with precision SAR ADCs.
In what ways does LM4050BEM3-2.0 compare to a bandgap reference with ±0.5% accuracy for a sensor interface?
LM4050BEM3-2.0 offers tighter ±0.2% initial accuracy versus a typical ±0.5% bandgap reference, reducing system offset error by 2.5× in sensor signal chains. For an 11-bit effective resolution requirement, the tighter tolerance prevents the reference error alone from consuming the full error budget at the 2.048 V output level.
