General Desc ription
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.
