GXSC voltage reference source GX34XX replaces REF34xx/MAX6070/71A/ADR34xx for industrial control applications

In the field of industrial control, voltage reference sources ensure sensor signal acquisition, precise actuator driving, and reliable operation of measuring instruments, achieving data calibration and error control. The complexity of industrial environments demands strict voltage reference sources, requiring ultra-low temperature coefficients and long-term stability to ensure the accuracy of operating conditions. General industrial equipment often operates at extreme temperatures ranging from -40 ℃ to 125 ℃, and the reference source needs to maintain a low temperature coefficient (<5ppm/℃) throughout the entire temperature range. This article mainly introduces a GX34XX voltage reference source PIN TO PIN replacement REF34xx/MAX6070/71A/ADR34xx, which helps industrial control achieve high-precision control.  

The voltage reference source GX34XX has the characteristics of low temperature drift (3ppm/° C), low power consumption, and high-precision CMOS. The initial accuracy of the device is ± 0.08%, low operating current, and power consumption is less than 125 μ A. GX34XX provides an extremely low output noise of 15 μ Vp-p/V, enabling it to maintain high signal integrity of high-resolution data converters in noise critical systems. The GX34XX low temperature coefficient voltage reference source can maintain stable output over a wide temperature range (-40 ℃ to 125 ℃).
