General Description

The MAX6006–MAX6009 ultra-low-power shunt refer-ences are ideal for space-critical and low-power appli-cations. They are offered in 3-pin SOT23 packages,and the minimum operating current is guaranteed to be <1μA. The devices feature low temperature coefficients of <30ppm/°C and initial accuracy of better than 0.2%.Available in +1.25V, +2.048V, +2.5V, and 3V output voltages, the MAX6006–MAX6009 have references of +1.25V, +2.048V, +2.5V, and +3.0V, respectively. The devices can be used as lower-power, higher-precision upgrades to the ICL8069, LM385, LT1004, and LM4040references. The MAX6006–MAX6009 are available in two grades: A and B. The A grade features a tempera-ture coefficient of 30ppm/°C over the extended temper-ature range of -40°C to +85°C, with an initial accuracy of 0.2%. Grade B features a temperature coefficient of 75ppm/°C with an initial accuracy of 0.5%. MAX6006in+1.25V and MAX6008 in +2.5V are offered in 8-pin SOIC packages, as plug in upgrades for LT1004 and LM285.

ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS —MAX6006

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

Note 2:This parameter is guaranteed by the “reverse breakdown change with current ” test.Note 3:TC is measured by the “box ” method; i.e., (V MAX - V MIN ) / (T MAX - T MIN ).

Note 4:Thermal hysteresis is defined as the change in the +25°C output voltage after cycling the device from T MIN to T MAX .
