The A grade offers +\/-0.05% initial accuracy with 3 ppm\/C typical temperature coefficient. Operating from 7-36 V with only 0.5 mA max quiescent current, it features 3 uV p-p noise in 0.1-10 Hz band and 25 ppm\/1000 hours long-term stability. Can source 10 mA and sink 5 mA.","working_principle":"The ADR02 uses a buried Zener reference topology. (1) Buried Zener: The breakdown junction is beneath the silicon surface, away from defects that cause noise and drift. The voltage is laser-trimmed to +\/-0.05%. (2) Temperature Compensation: Diode network compensates the positive tempco of the Zener, achieving 3 ppm\/C. (3) Error Amplifier: Buffers the Zener reference and drives the output with 0.05 Ohm output impedance. (4) Supply Regulation: 7 ppm\/V typical line regulation from 7-36 V.","pin_description":"
