The REF54 is a family of high precision, low-drift, low current consumption series voltage reference devices. The REF54 family offers low temperature drift coefficient (0.8ppm/°C), low-noise (0.11ppmp-p) and high accuracy (±0.02%) while consuming 380µA current. The REF54 with low long-term drift (3ppm LCCC; 25ppm SOIC), excellent load and line regulation helps meet strict performance requirements of high precision applications. The device family is designed as a companion device for high-resolution data converters such as ADS8900B , ADS127L11 , ADS1285 , and DAC11001B . The REF54 family supports wide supply voltage rating of 18V. The REF54 device supports up to 10mA load current. The REF54 is specified for the two temperature ranges, C grade is specified for from 0°C to 70°C and Q grade is specified for from –40°C to +125°C. The wide temperature range enables operation across various industrial applications.
