Description for the REF70

The REF70 device family offers a unique combination of very low noise (0.22 ppmp-p), low thermal drift (2 ppm/°C), and high accuracy (±0.025%). These characteristics of the REF70, when paired with high-resolution data converters, enable various end equipment to achieve their performance targets.

High initial accuracy with very low temperature and long-term drift help reduce the need for frequent in system calibration.

LCCC (FKH) package helps improve the long term drift and thermal hysteresis performance further for applications requiring a very stable reference.

REF70 is specified for the wide temperature range of −40°C to +125°C. The wide temperature range enables the device to operate across various applications. Contact the TI sales representative for additional voltage and package options.
