devices are available with output voltage options of 1.25V, 1.8V, 2.048V, 2.5V, 3V, 4.096V, 4.5V, and 5V. 20ppm/°C (max) Temperature Coefficient They feature a proprietary curvature-correction circuit

and laser-trimmed thin-film resistors that result in a very low temperature coefficient of 20ppm/°C (max) and an 2m A Sink Current initial accuracy of ±0.2% (max). Specifications apply to

the extended temperature range (-40°C to +85°C).

Stable with Capacitive Loads

The MAX6061–MAX6068 typically draw only 90µA of supply current and can source 5m A or sink 2m A of load 90µA (typ) Quiescent Supply Current current. Unlike conventional shunt-mode (two-terminal)
