With only 95uA supply current and 15uVp-p low-frequency noise, it is designed for precision ADC\/DAC reference and measurement applications. The output enable\/disable pin allows power sequencing.","working_principle":"The LM4120 uses a buried-zener bandgap reference core with precision laser-trimmed thin-film resistors for +\/-0.2% initial accuracy. The curvature-correction circuit compensates for the nonlinear temperature dependence of the bandgap voltage, achieving 10ppm\/C max drift. A high-gain error amplifier and series pass element buffer the reference core from load variations.","pin_description":"
