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 a tiny footprint. Using ADI's 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.
