Description
The LTC^®6652 family of precision, low drift, low noise
references is fully specified 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 perfor-
mance industrial and other high temperature applications.
The LTC6652 voltage references can be powered from
supply voltages up to 13.2V. They boast low noise, ex-
cellent 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 refer-
ence is not needed. The optional output capacitor can be
left off when space constraints are critical.
The LTC6652 references are offered in an 8-lead MSOP
package and an 8-lead LS8 package. The LS8 is a 5mm
× 5mm surface mount hermetic package that provides
outstanding stability.
