LTC6652
Precision Low Drift Low
Noise Buffered Reference
Features Description
n
Low Drift: The LTC 6652 family of precision, low drift, low noise
A-Grade 5ppm/C Max references is fully specified over the temperature range
B-Grade 10ppm/C Max (MSOP8) of 40C to 125C. High order curvature compensation
B-Grade 8ppm/C Max (LS8) allows these references to achieve a low drift of less than
n
High Accuracy: 5ppm/C with a predictable temperature characteristic and
A-Grade 0.05% Max an output voltage accuracy of 0.05%. The performance
B-Grade 0.1% Max over temperature should appeal to automotive, high perfor-

Low Power Shutdown: <2A Maximum
cellent load regulation, source and sink capability and
n
Thermal Hysteresis (LS8): 45ppm (40C to 125C)
exceptional line rejection, making them a superior choice
n
Long-Term Drift (LS8): 20ppm/kHr
for demanding precision applications. A shutdown mode

8-Lead MSOP and 5mm 5mm Surface Mount
The LTC6652 references are offered in an 8-lead MSOP
Hermetic Packages
package and an 8-lead LS8 package. The LS8 is a 5mm
a 5mm surface mount hermetic package that provides
outstanding stability.
