3 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 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 noisesensitive
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.
