Frequently Asked Questions
What is the initial accuracy of the LT1019CS8-5#PBF voltage reference and how does it affect ADC measurement error?
The LT1019CS8-5#PBF has a 0.2% initial accuracy on its 5 V output, meaning the output sits between 4.99 V and 5.01 V without trimming. For a 12-bit ADC with a 5 V full-scale reference, a 0.2% reference error introduces at most 8 LSB of gain error, which is acceptable for most industrial measurement applications without external calibration.
Can the LT1019CS8-5#PBF operate as both a series and shunt reference in the same circuit design?
Yes, the LT1019CS8-5#PBF supports series and shunt operating modes with its three-terminal architecture. In series mode it draws current from a single supply and regulates a 5 V output; in shunt mode it sinks current from a higher voltage source through a resistor, maintaining a stable 5 V across its terminals with output range from 4.35 V to 5.25 V.
What output voltage range does the LT1019CS8-5#PBF guarantee across its operating conditions?
The LT1019CS8-5#PBF guarantees an output voltage between 4.35 V and 5.25 V across its full operating temperature and supply voltage range. This 900 mV output window ensures the reference remains within specifications even under worst-case combinations of temperature drift, load variation, and initial trim error in production-volume designs.
For a precision industrial weigh scale design, why would a designer choose LT1019CS8-5#PBF over a lower-accuracy reference?
A precision industrial weigh scale with a 16-bit ADC requires the reference voltage to be accurate and stable to within 1–2 LSB. The LT1019CS8-5#PBF provides 0.2% initial accuracy and a low temperature coefficient, minimizing gain drift across the -40°C to +85°C industrial temperature range. Using a lower-accuracy 1% reference would introduce up to 655 LSB of gain error in a 16-bit system, making calibration-free operation impossible.
