Replacement for REF3012, Voltage Reference Source GX3012 Widely Used in Industrial Automation Applications

In industrial automation systems, accurate and stable voltage references are provided for measurement and control systems to ensure the accuracy and reliability of various sensors, transmitters and controllers.

Voltage reference source can be used as a stable reference voltage source for feedback control systems, PLC (programmable logic controller) and other equipment, but also to calibrate other voltage measurement equipment, to ensure the accuracy of the measurement of the entire industrial automation system

This article focuses on a voltage reference source GX3012, the device is a powerful, high stability precision CMOS voltage reference source chip for a variety of precision measurement and calibration applications, with a low temperature drift (10ppm/°C), ± 0.2% of the maximum initial accuracy, low operating current, power consumption of less than 125μA and other performance characteristics; and most ADCs and DACs are compatible with it is available in a small SOT-23 package.

The low hysteresis of the GX3012 output voltage and low long-term output voltage drift further improve stability and system reliability over a wide temperature range of -40°C to +125°C. In addition, the device‘s small size and low operating current (125ua) are more favorable for convenient battery-powered applications.
