Working principle

The working principle of the LT1634ACS8-1.25#PBF is based on a bandgap voltage reference circuit. It uses a voltage converter to generate a precise, accurately scaled reference voltage output that is independent of supply rail and temperature variations. A differential input signal is fed into the device and compared to an internal reference voltage. When the signal voltage is equal to the reference voltage, the converter output is saturated and the reference voltage is maintained constant. The voltage is then buffered to the output and regulated by the feedback amplifier.
