REF70 Description
The REF70 is a family of high precision series voltage references that offers the industry’s lowest noise (0.23 ppmp-p), very low temperature drift coefficient (2 ppm/°C), and high accuracy (±0.025%). The REF70 offers a high PSRR, low drop-out voltage and excellent load and line regulation to help meet strict transient requirements. This bination of precision.
