Voltage Reference Source GX5025 Replaces REF5025 for Digital Real-Time Oscilloscopes

Digital real-time oscilloscopes are oscilloscopes that utilize ultra-high bandwidth, ultra-low noise floor, and high ENOB to easily obtain the complete desired signal. Digital oscilloscopes mainly measure the shape of AC or pulsed current waves, and convert the measured voltage to digital information through A/D. Digital oscilloscopes capture a series of sample values of the waveform and then reconstruct the waveform.

 

In order to ensure the accuracy and integrity of the signals measured by the oscilloscope, a voltage reference source is generally required to maintain a constant output voltage.GXSC‘s ultra-low-noise, low-temperature-drift GX5025 voltage reference source has a 1/f noise voltage of only 4.8μVpp, and a typical temperature drift of 10ppm/°C from -20°C to 90°C. Even if the ambient temperature or power supply voltage changes, the voltage reference source will not be affected, and other chips can be referenced to the same voltage reference source. Other chips can refer to this voltage reference to measure with the required accuracy.

 

The GX5025 chip is described as follows:

1, GX5025 can operate between 2.8V and 5.5V, with an operating current of 270μA and a maximum load current of 10mA.

2, GX5025 provides 1.25V, 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V and 5.0V voltage options.

3, GX5025 provides low temperature drift and low noise indicators are conducive to improve system accuracy, suitable for high-precision industrial design.

4, GX5025 operating at -40 ℃ to +125 ℃ temperature range, and a small 8-pin SOIC package.

5, GX5025 voltage reference source with its high accuracy characteristics, in addition to data converters in addition to process control, precision instrumentation, precision current source and other application scenarios also has outstanding performance advantages.

6, GX5025 voltage reference source has been mass production, can provide a more cost-effective replacement program for imported chips.
