3 Description
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 (0.8 ppm/°C), low noise (0.11 ppmp-p)
and high accuracy (±0.02) while consuming 260
μA current. The REF54 with low long-term drift (25
ppm), 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 18 V. The wide supply range allows for direct
connection to the battery or field supply. This also
protects the device in case of power supply IC
failure. The REF54 device supports up to 10 mA
load current. The wide load current support allows
for direct connection of REF54 as power supply to
precision sensors.
The REF54 is specified for the wide temperature
range of −40°C to +125°C. The wide temperature
range enables operation across various automotive
and industrial applications.
