General Description The accurate 2.5V and 4.096V MAX872/MAX874 microvoltage references consume a maximum of 10µA of supply voltage and operate up to 20V. This combination of ultra-low quiescent current and low 200mV dropout makes them ideal for battery-powered devices. Their sources and sinks are only up to 500µA with a 200mV input voltage headroom, which makes the 2.5V MAX...

General description Packaged in SOT23, the low-cost MAX6001-MAX6005 series series voltage references match the cost-advantage of parallel references and offer the power-saving advantages of a series of references that traditionally cost more. Unlike traditional parallel mode (2-terminal) references that must bias the load current and therefore require an external resistor, these device...
