Create +/-12V Split Rail From A 5V Bias
https://www.electronics-lab.com/create-12v-split-rail-5v-bias/
With digital semiconductor technology driving system power supplies to lower voltages for higher performance and lower system power, sensitive analog sensor circuits face a growing problem. Much of the inherent noise created in the early stages of an analog sensor signal path is independent of the amplifier bias voltage, so using a higher bias voltage […]
