MAXIM MAX875AESA+

The MAX873/MAX875/MAX876 precision 2.5V, 5V, and 10V references offer excellent accuracy and very low power consumption. Extremely low temperature drift combined with excellent line and load regulation permit stable operation over a wide range of electrical and environmental conditions. Operation for the MAX873 is guaranteed with a +4.5V supply, making the part ideal in systems running from a +5V±10% supply. Low 10Hz to 1kHz noise—typically 3.8µV RMS, 9µV RMS, and 18µV RMS, respectively, for the MAX873, MAX875, MAX876—make the parts suitable for 12-bit data-acquisition systems. A TRIM pin facilitates adjustment of the reference voltage over a ±6% range, using only a 100kΩ potentiometer. A voltage output proportional to temperature provides a source for temperature compensation circuits, temperature warning circuits, and other applications.
