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.
