GXSC Voltage Reference Source Replaces RFE3012 in Test and Measurement Equipment

The mission of test and measurement equipment is to accurately obtain the values of various physical quantities, while the voltage reference source, as the source of providing a stable reference voltage, directly determines the accuracy of the measurement. In electronic measuring instruments, such as digital multimeter for voltage, current, resistance and other parameters of the measurement, the first need to be measured signal and reference voltage comparison.

Voltage measurement, for example, if the voltage reference source output voltage deviation, the measurement results are bound to be inaccurate. High-quality voltage reference source can control the output voltage accuracy in a very small range, for scientific research experiments, industrial production quality testing and other demanding precision scenarios, to provide a reliable data support.

This paper recommends the use of GXSC low temperature drift (10ppm / ° C), low power consumption, precision CMOS reference voltage source, can PIN TO PIN replacement SHR3012, the voltage reference source with ± 0.2% of the maximum initial accuracy, low operating current, power consumption of less than 125 ua. Compatible with the majority of the ADC and DAC, which provides a small SOT-23 package.

Test and measurement equipment is often required to work in different environmental conditions, temperature fluctuations, supply voltage changes and electromagnetic interference and other factors, may affect its performance. The stability of the voltage reference source is critical here. The low output voltage hysteresis and low long-term output voltage drift of the GXSR voltage references further enhance system stability and reliability. In addition, the small size and low operating current (125 PA) of these devices are very favorable for portable test and measurement equipment.
