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 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.
The MAX6190‑MAX6198 family from Maxim Integrated provides precision, micropower, low‑dropout voltage references with high initial accuracy and very low temperature coefficient. These bandgap references draw a maximum of 35 pA quiescent supply current, making them suitable for battery‑powered instruments and applications requiring fast settling and stability with capacitive loads up to 2.2 nF.
The series includes multiple output voltage options (1.25 V to 5 V) and offers features such as 100 mV dropout at 500 µA load, 0.12 %/µA load regulation, and line regulation as low as 8 µV/V. Absolute maximum ratings, electrical characteristics, and ordering information are detailed for each part number.
