Download Complete Datasheet for Details

The LT®1027 is a precision reference with extra-low drift, superior accuracy, excellent line and load regulation and low output impedance at high frequency. This device is intended for use in 12- to 16-bit A-to-D and D-to-A systems where demanding accuracy requirements must be met without the use of power hungry, heated substrate references. The fast settling output recovers quickly from load transients such as those presented by A-to-D converter reference inputs. The LT1027 brings together both outstanding accuracy and temperature coefficient specifications.

The LT1027 reference is based on LTC’s proprietary advanced subsurface Zener bipolar process which eliminates noise and stability problems associated with surface breakdown devices.
