DESCRIPTION
The LTC
references is fully specifi ed over the temperature range
of –40°C to 125°C. High order curvature compensation
allows these references to achieve a low drift of less than
5ppm/°C with a predictable temperature characteristic and
an output voltage accuracy of ±0.05%. The performance
over temperature should appeal to automotive, high-
performance industrial and other high temperature
applications.
The LTC6652 voltage references can be powered from a
13.2V supply or as little as 300mV above the output voltage
or 2.7V; whichever is higher. The LTC6652 references
are offered in an 8-Lead MSOP package. They boast low
noise, excellent load regulation, source and sink capability
and exceptional line rejection, making them a superior
choice for demanding precision applications. A shutdown
mode allows power consumption to be reduced when the
reference is not needed. The optional output capacitor can
be left off when space constraints are critical.
