The ADR361 are precision 2.500 V band gap voltage references that offer low power and high precision in a compact TSOT package. Using proprietary temperature drift curvature correction techniques from Analog Devices, Inc., the ADR361 references achieve a low temperature drift of 9 ppm/°C in a TSOT package.

The ADR361 of micropower, low dropout voltage references provide a stable output voltage from a minimum supply of 300 mV greater than the output. The advanced design of the devices 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 ADR361 precision voltage references ideally suited for battery-operated applications.
