The REF70 is a family of high precision series voltage references that offers the industry’s lowest noise (0.23 ppm p-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 combination of precision and features is designed for applications such as test and measurement that demand a precise reference to be paired with precision, high-resolution data converters such as ADS8900B, ADS127L01 and DAC11001A, to achieve optimal performance in the signal chain. The REF70 is also designed for noise-sensitive medical applications such as ultrasound and X-ray to help enable low-noise measurements from the analog front end.

The REF70 family is available in VSSOP and LCCC package options. The LCCC (FKH) package is a hermetically sealed ceramic package that allows for low, long-term drift for applications that require a stable reference over a long time period without calibration.

The REF70 is specified for the wide temperature range of −40°C to +125°C. The wide temperature range enables operation across various industrial applications.
