Description

The MAX873/MAX875/MAX876 precision 2.5V, 5V, and10V references offer excellent accuracy and very lowpower consumption. Extremely low temperature driftcombined with excellent line and load regulation permitstable operation over a wide range of electrical and environmentalconditions. Operation for the MAX873 is guaranteedwith a +4.5V supply, making the part ideal insystems running from a +5V ±10% supply. Low 10Hz to1kHz noise—typically 3.8µVRMS, 9µVRMS, and 18µVRMS, respectively, for the MAX873, MAX875, MAX876—make the parts suitable for 12-bit data-acquisition systems.A TRIM pin facilitates adjustment of the reference voltageover a ±6% range, using only a 100kΩ potentiometer. Avoltage output proportional to temperature provides asource for temperature compensation circuits, temperaturewarning circuits, and other applications.Applications12-Bit ADCs and DACsDigital MultimetersLow-Power Test EquipmentPortable Data-Acquisition Systems
