GENERAL DESCRIPTION
The ADR130 is the industry’s first family of tiny, micropower,
low voltage, high precision voltage references. Featuring 0.35%
initial accuracy and 25 ppm/°C of temperature drift in the tiny
TSOT-23 package, the ADR130 voltage reference only requires
80 μA for typical operation. The ADR130 design includes a
patented temperature drift curvature correction technique that
minimizes the nonlinearities in the output voltage vs. tempera-
ture characteristics.
