GENERAL DESCRIPTION

The ADR360/ADR361/ADR363/ADR364/ADR365/ADR366

are precision 2.048 V, 2.5 V, 3.0 V, 4.096 V, 5.0 V, and 3.3 V band

gap voltage references that feature low power, high precision in

tiny footprints. Using Analog Devices’ patented temperature

drift curvature correction techniques, the ADR36x references

achieve a low temperature drift of 9 ppm/°C in the TSOT

package.

The ADR36x family of micropower, low dropout voltage

references provides a stable output voltage from a minimum

supply of 300 mV above the output. Their advanced design

eliminates the need for external capacitors, which further

reduces board space and system cost. The combination of low

power operation, small size, and ease of use makes the ADR36x

precision voltage references ideally suited for battery-operated

applications.
