1µA SOT23 Precision Shunt
Voltage Reference
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 LM4040
references. 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%. MAX6006
in+1.25V and MAX6008 in +2.5V are offered in 8-pin
SOIC packages, as plug in upgrades for LT1004 and
LM285.
