MAX6190–MAX6195/MAX6198Precision, Micropower,Low-Dropout Voltage ReferencesGeneral DescriptionFeatures The MAX6190–MAX6195/MAX6198 precision, micro- ♦ ±2mV (max) Initial Accuracy power, low-dropout voltage references offer high initial accuracy and very low temperature coefficient through ♦ 5ppm/°C (max) Temperature Coefficient a proprietary curvature-correction circuit and laser- ♦ 35µA (max) Supply Current trimmed precision thin-film resistors. ♦ 100mV Dropout at 500µA Load Current These series-mode bandgap references draw a maxi- mum of only 35µA quiescent supply current, making ♦ 0.12µV/µA Load Regulation them ideal for battery-powered instruments. They offer ♦ 8µV/V Line Regulation 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. Applications These devices are internally compensated, making Hand-Held Instruments them ideal for applications that require fast settling, Analog-to-Digital and Digital-to-Analog Converters and are stable with capacitive loads up to 2.2nF.
