Product Summary
The LTC2981AIGN-1#PBF is an I2C Programmable Precision Reference with EEPROM. It combines an ultralow drift reference, a precise low drift 8-bit adjustment DAC, a low drift, low noise buffer and internal EEPROM. While external pins or internal register bits set the central output voltage, an 8-bit I2C DAC adjusts this mid-scale output with a selectable, relative ±1% or ±10% range. Both mid-scale output voltage level and DAC settings can be stored in EEPROM and restored upon power-up. The LTC2981BCGN#PBF accepts input voltages between 2.9V and 15V. Both references offer extremely good accuracy over temperature with 10ppm/℃ drift. The applications of the LTC2981BCGN#PBF include Precision Reference, Instrumentation and Process Control, Data Acquisition Systems, Test Equipment, Power Supply Margining, Medical Equipment.
