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. , LTC and LT are registered trademarks of Linear Technology Corporation.
