Description : Low Power, Low Noise Voltage References with Sink/Source Capability

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 offer low power and high precision in tiny footprints. Using patented temperature drift curvature correction techniques from Analog Devices, Inc., the ADR36x References achieve a low temperature drift of 9 ppm/°C in a 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.
