General Description

The MAX6190–MAX6195/MAX6198 precision, micro-

power, low-dropout voltage references offer high initial

accuracy and very low temperature coefficient through

a proprietary curvature-correction circuit and laser-

trimmed precision thin-film resistors.

These series-mode bandgap references draw a maxi-

mum of only 35µA quiescent supply current, making

them ideal for battery-powered instruments. They offer

a supply current that is virtually immune to input volt-

age variations. Load-regulation specifications are

guaranteed for source and sink currents up to 500µA.

These devices are internally compensated, making

them ideal for applications that require fast settling,

and are stable with capacitive loads up to 2.2nF.
