General Description
The MAX6070/MAX6071 offer a very low noise and
low-drift voltage reference in a small 6-pin SOT23 package.
These devices provide a 1/f noise voltage of only
4.8µV
P-P
at an output voltage of 2.5V, with a temperature
drift of 6ppm/NC (max). The devices consume 150FA of
supply current and can sink and source up to 10mA of load
current. The low-drift and low-noise specifications enable
enhanced system accuracy, making these devices ideal
for high-precision industrial applications. The MAX6070
offers a noise filter option for wideband applications.
The devices are available in a 6-pin SOT23 package and
are specified over the extended industrial temperature
range of -40NC to +125NC. The 2.5V options are also
available in a 6-bump 0.78mm x 1.41mm wafer-level
package (WLP).
