LTC6655 - Precision Buffered Reference


Linear Technology’s bandgap references are low noise, low drift, precision voltage references fully specified over the -40°C to 125°C temperature range


LTC6655 - Precision Buffered Reference FamilyThe low noise and drift of Linear Technology's LTC6655 references are ideally suited for the high- resolution measurements required by instrumentation and test equipment, while the wide temperature range supports automotive and industrial applications. Advanced curvature compensation allows these bandgap references to achieve a drift of less than 2ppm/°C with a predictable temperature characteristic and an output voltage accurate to ±0.025 percent, reducing or eliminating the need for calibration.

The LTC6655 low dropout series references can be powered from as little as 500mV above the output voltage or as much as 13.2V. Superior load regulation and source and sink capabilities coupled with exceptional line rejection give consistent performance over a wide range of line and load 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 precision applications.
