MAXIM MAX6190, MAX6195, MAX6198 Technical data

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.
Features
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/µA Load Regulation
o 8µV/V Line Regulation
Applications
Hand-Held Instruments
Analog-to-Digital and Digital-to-Analog Converters
Industrial Process Control
Precision 3V/5V Systems

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
