Voltage Reference Source GX1025 Compatible with MAX6070 for Power Quality Analyzers

In the face of emerging applications such as artificial intelligence or human-computer interaction, it is necessary to collect a variety of analog environmental data, and through its conversion, analysis and learning, the system can make predictable and accurate responses to changes in the environment. In this process, how to achieve accurate measurement in analog-to-digital conversion is a key link, and to achieve this goal, a voltage reference source that is not affected by the input voltage or ambient temperature conditions and does not fluctuate with the system is essential.

Voltage references are precision analog devices designed to maintain a constant output voltage even when parameters such as ambient temperature or supply voltage change, and other ICs can refer to this voltage reference to make measurements with the required accuracy. Voltage references, with their high accuracy, can be useful in applications other than data converters. This article introduces the GX1025, an ultra-low-noise, low-temperature-drift voltage reference for use in power quality analyzers to minimize power consumption and extend battery life.

GX1025 can provide up to ± 0.04% initial accuracy, ± 0.2% initial accuracy, low temperature drift and low noise indicators are conducive to improving the accuracy of the system, ideally used for high-precision measurements and power quality analyzer design, in addition to noise filter options can be provided to meet the requirements of broadband applications.
