MAX6190A

19-1408; Rev 1; 3/99 Precision, Micropower, Low-Dropout Voltage References General Description The MAX6190–MAX6195/MAX6198 precision, micropower, low-dropout voltage references offer high initial accuracy and very low temperature coefficient through a proprietary curvature-correction circuit and lasertrimmed precision thin-film resistors. These series-mode bandgap references draw a maximum of only 35µA quiescent supply current, making them ideal for battery-powered instruments. They offer a supply current that is virtually immune to input voltage 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. o ±2mV (max) Initial Accuracy o 5ppm/°C (max) Temperature Coefficient o 35µA (max) Supply Current o 100mV Dropout at 500µA Load Current o 0.12µV/V Load Regulation o 8µV/V Line Regulation Features MAX6190–MAX6195/MAX6198 Applications Hand-Held Instruments Analog-to-Digital and Digital-to-Analog Converters Industrial Process Control Precision 3V/5V Systems Hard-Disk Drives Selector Guide PART MAX6190A MAX6190B MAX6190C MAX6191A MAX6191B MAX6191C MAX6192A MAX6192B MAX6192C MAX6193A MAX6193B MAX6193C MAX6198A MAX6198B MAX6198C MAX6194A MAX6194B MAX6194C MAX6195A MAX6195B MAX6195C OUTPUT VOLTAGE (V) 1.250 1.250 1.250 2.048 2.048 2.048 2.500 2.500 2.500 3.000 3.000 3.000 4.096 4.096 4...
