The NSREF30/31XX series products include NSREF30XX and NSREF31XX two sub -series. Each sub -series can be divided into 6 different models, corresponding to different output voltages.Each product has car regulations and construction regulations. Among them, car-level products meet the reliability requirements of AEC-Q100 Grade1, and can be competent in the strict environment of -40 ~ 125 ° C.

High initial accuracy, low temperature drift

NSREF30/31XX achieves high initial accuracy and low temperature drift performance, and its initial accuracy is ± 0.2%, that is, the guarantee of its output accuracy at two thousandths of the ideal value at room temperature.Performance, the temperature drift of NSREF30XX is a typical value of 10ppm/℃, the maximum value of 35ppm/℃, and the temperature drift of NSREF31XX is a typical value of 5ppm/℃, the maximum value of 15ppm/℃.So as to ensure that within the full temperature, help customers achieve high accuracy of ADC sampling.

Low noise, low power consumption

At the benchmark output end, the noise output of low frequency 0.1Hz ~ 10Hz is an important part of the ADC sampling error.

NSREF30/31xx Sample advanced craftsmanship and special low noise design, only 20UVPP at 2.5V(Typical values) noise, and the noise distribution is relatively convergent, the 1sigma value is less than 2UVPP. Greatly reduce the effect of low -frequency noise on ADC sampling errors.Under the premise of ensuring low noise, only 130UA (typical values) current consumes the work scenarios such as industrial site transmitters, electricity, portable measurement equipment.

Low power adjustment rate and load adjustment rate

The power supply adjustment rate indicates that when the input power is changed, the voltage benchmark output remains stable.In the occasion where the power supply voltage is unstable or is susceptible to interference, the low power adjustment rate can make the sampling accuracy from unstable the impact of unstable power supply voltage or power supply interference. NSREF30/31xx can provide a low power adjustment rate of 20ppm/V in 2.5V output at 2.5V output.Essence

The corresponding load adjustment indicates the ability to maintain a stable voltage benchmark output when the input power changes.NSREF30/31XX can provide 8UV/MA load adjustment rate.

Low work pressure difference, no requirements for output capacitance

Thanks to the internal good circuit design, NSREF30/31xx only requires that the input voltage is 1mV higher than the output voltage 1mV to normal output operating voltage (except NSREF3012/3112 requires a minimum 1.8V operating voltage).Friendly, such as battery power supply, battery voltage will be reduced.NSREF30/31XX does not require the output capacitor.It can also work normally without the output capacitor, and it will not work abnormal work due to the failure of the capacitance or failure. As the output capacitor value increases, it can support the stable capacitor value range of the loop.Application circuits and scenarios have expanded the boundary conditions of its application.
