MAX672/673 reference voltage circuit (+10V) has thefeatures such as high accuracy, low temperature drift. Input voltage of MAX672 is 10V, of MAX673 is 5V. For this circuit, the input voltage error ±0.05% and output voltage can be adjusted slightly. The typical temperature drift is 2×10-6/℃, typical value of stable load is 0.001%, and no-load maximum input current is 1.4mA. The maximum output voltage is 40V. Working temperature of MAX672M/673M is -55~+125℃, MAX672E/673E -40~+85℃,. MAX672C/673C 0~+70℃.. The circuit itself has an interior short-circuit-proof circuit. Output voltage of TEMP terminal of MAX673 linearly changes with temperature. For MAX672M/673, only metal encapsulation and DIP ceramic encapsulation are available.
