AQ4041
Precision Micropower
Shunt Voltage Reference
SOT23, SC70, and TO92 Package
Product Specification
Revision 1.1
June 14, 2007
General Description
The AQ4041 is a precision voltage
reference offered in very small packages
SOT23 and SC70 for applications where
power and space are critical. Its precision
reference is trimmed during wafer sort to
insure accuracy and tight distributions
centered at 1.225V. The minimum
operating current is less than 40 µA to keep
power consumption at a minimum. The
bandgap reference has curvature correction
and low dynamic impedance to ensure
stable accuracy over a wide range of
operating currents and temperatures

Absolute Maximum Ratings
Stress greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the
device. These stress ratings only, and functional operation of the device at these or any conditions beyond
those indicated under recommended Operating Conditions is not implied. Exposure to “Absolute Maximum
Rating” for extended periods may affect device reliability. Use of standard ESD handling precautions is
required.
