AQ4041 Precision Micropower Shunt Voltage Reference SOT23, SC70, and TO92 Package Product Specification Revision 1.1 General Description June 14, 2007 Applications 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 • • • • Power supplies Low TC low voltage reference Portable, Battery-Powered Equipment Instrumentation Features • Offered in small packages: SOT23 and • • • • SC70 40uA to 12mA operation Low TC voltage reference 100ppm/ºC Stable with no load capacitance RoHS compliant Pin Configuration Pin Descriptions Pin Name Function CATH + Input, nominally 1.225V in normal operation.

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.
