MAX6006–MAX6009
1µA SOT23 Precision Shunt
Voltage Reference
General Description
Features
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%.
● Ultra-Low Operating Current: Guaranteed < 1µA
● Small 3-Pin SOT23 Package
● Initial Voltage Accuracy: 0.2%
● Temperature Coefficient: 30ppm/°C max
● Temperature Range: -40°C to +85°C
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 SO
packages, as plug in upgrades for LT1004 and LM285.
● Factory-Trimmed Output Voltages: +1.25V, +2.048V,
+2.5V, +3.0V
● Wide Operating Range: 1µA to 2mA
● AEC-Q100 (MAX6008AEUR/V+ Only)
Applications
● Battery-Powered Equipment
● Portable Meters
● Precision Regulators
● A/D and D/A Converters
