MAXIM MAX6006, MAX6009 Technical data
General Description
The MAX6006–MAX6009 ultra-low-power shunt references are ideal for space-critical and low-power applications. 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 LM4040
references. The MAX6006–MAX6009 are available in
two grades: A and B. The A grade features a temperature coefficient of 30ppm/°C over the extended temperature 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%. MAX6006
in+1.25V and MAX6008 in +2.5V are offered in 8-pin
SOIC packages, as plug in upgrades for LT1004 and
LM285.

ELECTRICAL CHARACTERISTICS—MAX6006
(TA= -40°C to +85°C, unless otherwise noted. Typical values are at TA= +25°C.) (Note 1)
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.
