MAX6190MAX6195/MAX6198 Precision, Micropower, Low-Dropout Voltage References General Description Features The MAX6190MAX6195/MAX6198 precision, micro- 2mV (max) Initial Accuracy power, low-dropout voltage references offer high initial 5ppm/C (max) Temperature Coefficient accuracy and very low temperature coefficient through a proprietary curvature-correction circuit and laser- 35A (max) Supply Current trimmed precision thin-film resistors. 100mV Dropout at 500A Load Current These series-mode bandgap references draw a maxi- 0.12V/A Load Regulation mum of only 35A quiescent supply current, making them ideal for battery-powered instruments. They offer 8V/V Line Regulation a supply current that is virtually immune to input volt- age variations. Load-regulation specifications are Applications guaranteed for source and sink currents up to 500A. 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.
