High precision, low-temperature drift, low-noise voltage reference source GX4520/4525/4540 replaces ADR4520/4525/4540 for application in precision instruments and meters

High precision instruments and meters are the core cornerstone supporting technological progress and industrial upgrading in the industry. For example, in the manufacturing industry, high-precision measuring equipment can ensure precision control in the production process, improve product quality and production efficiency. Among them, the voltage reference source can achieve error control with stable and accurate reference voltage. The GXSC high-precision, low-temperature drift, low-noise voltage reference source GX4520/4525/4540 PIN TO PIN replaces ADR4520/4525/4540, making it an ideal reference choice for precision instruments and meters.

GX4520/4525/4540 is a high-precision, low-temperature drift, low-noise, and low-power voltage reference source. The absolute voltage accuracy of GX4520/4525/4540 can reach within ± 0.1%. In the working temperature range of -40 ℃~125 ℃, the typical temperature drift is 10ppm/℃, and the extremely low-temperature drift version has a temperature drift as low as 3ppm/℃. Low error can effectively avoid the influence of environmental temperature on accuracy.

In industrial application scenarios, excessive noise from the voltage reference source can cause measurement data fluctuations and affect structural stress analysis. When the output voltage of GX4520/4525/4540 is 2.048V, the 1/f noise voltage is 9 μ Vpp, and the power suppression ratio is as high as 60dB in the range of 0Hz~1KHz. In addition, the working voltage range of the device is 3.1V~5.5V, the typical static working current is 900 μ A, and the maximum load current is ± 10mA. GX4520/4525/4540 low-voltage reference sources are all packaged in 8-pin SOIC, and the working temperature range is -40 ℃~125 ℃.
