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.
