Using patented supply of 300 mV above the output. Their advanced design temperature drift curvature correction techniques from Analog eliminates the need for external capacitors, which further Devices, Inc., the ADR39x references achieve a low 9 ppm/C of reduces board space and system cost. The combination of low temperature drift in the TSOT package. power operation, small size, and ease of use makes the ADR39x precision voltage references ideally suited for battery-operated applications.
