At present, voltage reference source products are required in almost all advanced electronic products. Voltage reference sources are independent and can also be integrated into devices with more functions. For example:
1. In a data converter, the reference source provides an absolute voltage that is compared with the input voltage to determine the appropriate digital output.
2. In a voltage regulator, the reference source provides a known voltage value, which is compared with the output to obtain a feedback for adjusting the output voltage.
3. In a voltage detector, the reference source is used as a threshold to set the trigger point.
And for different types of voltage reference sources, their key indicators and issues to be comprehensively considered in the design process. It can provide information for designers to choose the optimal voltage reference source. The domestically produced GREF0530L is an ultra-low noise, low-temperature drift voltage reference source. Its low-temperature drift and low noise indicators are conducive to improving system accuracy and are very suitable for high-precision industrial design.

GREF0530L offers voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3.0V, 3.3V, 4.096V, and 5.0V (5V voltage option, power supply voltage needs to be between 5.3V and 5.5V). When the output voltage is 2.5V, the 1/f noise voltage is only 4.8 μ Vpp, typical temperature drift from -20 ℃ to 90 ℃ is 10ppm/° C. GREF0530L can operate between 2.8V and 5.5V, with a working current of 270 μ A. The maximum load current is 10mA.
GREF0530L chip features:
10ppm/C ultra-low temperature drift, 270uA low operating current
10mA driving current, 200mV low voltage difference
76dB ripple suppression
Adopting SOIC-8 small package
Working temperature range: -40 ℃ to+125 ℃
0.1uF-10uF load capacitor stability (optional)
