voltage references featuring ±0.02% maximum initial error, ADR4520 2.048 excellent temperature stability, and low output noise. ADR4525 2.5 This family of voltage references uses an innovative core ADR4530 3.0 topology to achieve high accuracy while offering industry-leading ADR4533 3.3 temperature stability and noise performance. The low, thermal y ADR4540 4.096 induced output voltage hysteresis and low long-term output ADR4550 5.0 voltage drift of the devices also improve system accuracy over time and temperature variations.
