0.25ppm Noise, Low Drift

Precision Buffered

Reference Family

voltage references, offering exceptional noise and drift

performance. This low noise and drift is ideally suited for

thehighresolutionmeasurementsrequiredbyinstrumenta-

tion and test equipment. In addition, the LTC6655 is fully

specified over the temperature range of –40°C to 125°C,

ensuring its suitability for demanding automotive and

industrialapplications.Advancedcurvaturecompensation

allowsthisbandgapreferencetoachieveadriftoflessthan

2ppm/°C with a predictable temperature characteristic

and an output voltage accurate to ±0.025%, reducing or

eliminating the need for calibration.

The LTC6655 can be powered from as little as 500mV

above the output voltage to as much as 13.2V. Superior

load regulation with source and sink capability, coupled

with exceptional line rejection, ensures consistent per-

formance over a wide range of operating conditions. A

shutdown mode is provided for low power applications.

Available in a small MSOP package, the LTC6655 family

of references is an excellent choice for demanding preci-

sion applications.
