Frequently Asked Questions
What is the output accuracy of TL4050B10IDCKRG4, and how does it affect ADC reference precision?
The TL4050B10IDCKRG4 provides a 10 V output with ±0.2% initial accuracy, meaning the output falls between 9.98 V and 10.02 V. For a 12-bit ADC referenced at 10 V, this ±20 mV accuracy contributes roughly ±8 LSB of reference error, which is acceptable for most industrial measurement applications without trimming or external calibration.
How should a bias resistor be selected for TL4050B10IDCKRG4 in a 12 V supply circuit?
With a 12 V supply and the TL4050B10IDCKRG4 reference at 10 V, the voltage across the series resistor is 2 V. For 1 mA cathode current, set the resistor to 2 kΩ. The device operates from 100 µA to 15 mA, so the resistor value can range from 133 Ω to 20 kΩ depending on the required load current and supply voltage.
In which precision measurement applications is TL4050B10IDCKRG4 commonly used as a reference?
The TL4050B10IDCKRG4 is used in industrial data acquisition front-ends, precision weigh scales, and calibration sources where a 10 V reference reduces the full-scale error of 16-bit or higher ADCs. It also serves as the reference in digital-to-analog converters for process control outputs in 4 mA to 20 mA current loop transmitters.
How does TL4050B10IDCKRG4 compare to TL431 for a 10 V reference application?
The TL4050B10IDCKRG4 offers a fixed 10 V ±0.2% precision reference without external resistor-divider programming, while the TL431 requires two external resistors to set 10 V and has a lower initial accuracy of ±0.5% in the B grade. For applications demanding tighter 10 V accuracy with fewer external components, TL4050B10IDCKRG4 is the better choice.
