General Description：

The MAX872/MAX874 precision 2.5V and 4.096V micropower voltage references consume a maximum of only10µA and operate from supply voltages up to 20V. Thecombination of ultra-low quiescent current and low200mV dropout makes them ideal for battery-poweredequipment. They source and sink up to 500µA with only200mV input voltage headroom, which makes the 2.5VMAX872 ideal for use with a 3V supply and the 4.096VMAX874 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 makethese references suitable for a wide range of precisionapplications.
