The LT1027 is a precision reference voltage from Linear Technology Corporation that features ultra-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/D and D/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/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.
The LT1027 is a precision voltage reference designed for high-accuracy applications such as A-to-D and D-to-A converters, digital voltmeters, and reference standards. It offers superior accuracy with an extra-low temperature coefficient of 2ppm/°C maximum (LT1027A/B) and excellent long-term stability.
