10µA, Low-Dropout, Precision Voltage Reference
Not Recommended for New Designs
This product was manufactured for Maxim by an outside wafer foundry
using a process that is no longer available. It is not recommended for
new designs. The data sheet remains available for existing users.
A Maxim replacement or an industry second-source may be available.
Please see the QuickView data sheet for this part or contact technical
support for assistance.

0μA, Low-DropoutPrecision Voltage Reference
General Description
The MAX872/MAX874 precision 2.5V and 4.096V micro-
power voltage references consume a maximum of only
10μA and operate from supply voltages up to 20V. The
combination of ultra-low quiescent current and low
200mV dropout makes them ideal for battery-powered
equipment. They source and sink up to 500μA with only
200mV input voltage headroom, which makes the 2.5V
MAX872 ideal for use with a 3V supply and the 4.096V
MAX874 ideal for use with a 5V supply.
Initial accuracy of 0.2% at +25°C (±5mV for the MAX872,
±8mV for the MAX874) and low 40ppm/°C max drift make
these references suitable for a wide range of precision
applications.

(VIN= 2.7V, IL= 0mA, TA= +25°C, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
