This family of voltage references uses an innovative core

topology to achieve high accuracy while offering industry-leading

temperature stability and noise performance. The low, thermally

induced output voltage hysteresis and low long-term output

voltage drift of the devices also improve system accuracy over

time and temperature variations.
