The LT

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.
