GXSC high-precision benchmark source products support new energy and Industry 4.0

The reference voltage source is an important component of the data acquisition system, used to provide stable and accurate voltage output reference to ensure the accuracy and precision of the acquisition system. At the same time, the reference voltage source technology is also the base technology of BMS and precision signal chain chips.

The Guoxin Sichen voltage reference source can output different voltages such as 1.2V, 1.8V, 2.048V, 2.5V, 3V, 3.3V, 4.096V, and 5V. The entire process of chip selection, design and development, and production testing follows strict automotive regulations and has been tested by CNAS certified laboratory AEC-Q100 Grade-1 to ensure reliable and stable reference sources for the system under complex temperature, humidity, and stress conditions.

High precision low-temperature float:

The chip provides an initial accuracy of up to ± 0.08% (MAX), and it is well known that the initial accuracy of benchmark chips is easily affected by welding stress. This series specially optimizes the thermal characteristics of the device to ensure that the device still maintains an initial accuracy of ± 0.08% (MAX) after welding. At the same time, it can provide full temperature (-40~125 ℃) bleaching up to a maximum of 8ppm/℃.

Extremely low power and load adjustment rates:

The output accuracy of the benchmark chip is also affected by load and power supply changes. This series provides an output current load adjustment rate of 5ppm/mA, which means that when outputting 1mA current, the output voltage only changes by 5ppm; At the same time, it provides good power suppression capability, and when the power supply voltage changes by 1V, the output voltage only changes by 15ppm. Good power regulation and load regulation can ensure that the benchmark chip still provides accurate output in complex dynamic environments.

Good long-term stability and low power consumption

This series provides excellent long-term stability in the industry, with a typical change of 45ppm after 1000 hours of initial power on, ensuring the long-term accuracy of the system. At the same time, the power consumption is extremely low, with a typical power consumption of 125uA at room temperature and less than 150uA across the entire temperature range. While reducing system power consumption, the self heating effect of the chip is also reduced to ensure the accuracy of the output voltage.
