SNAS781D – OCTOBER 2020 – REVISED DECEMBER 2021

REF70 2 ppm/°C Maximum Drift, 0.23 ppm_p-p1/f Noise, Precision Voltage Reference

1 Features

3 Description

•

Low noise enables precision measurements:

– 1/f Noise (0.1 Hz to 10 Hz): 0.23 ppm_p-p

– 10 Hz to 1 kHz: 0.35 ppm_rms

Low temperature drift coefficient:

– 2 ppm/°C maximum (-40°C to 125°C)

High accuracy: ±0.025% maximum

Humidity resistant hermetic ceramic package

(LCCC)

Low long-term stability (1k hr): 28 ppm

Low dropout: 400 mV

Designed for a wide range of applications:

– Wide input voltage up to 18 V

– Output current: ±10 mA

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.

•

– Voltage options: 1.25 V, 2.5 V, 3 V, 3.3 V, 4.096

V, 5 V

Ultra-flexible solution:

•

– Stable with 1-μF to 100-μF output low-ESR

capacitor

– High PSRR: 107 dB at 1 kHz

– Operating temperature range: −40°C to +125°C

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.

2 Applications

•

Semiconductor test equipment

Precision data acquisition systems

Precision weight scales

Ultrasound scanner

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.

X-ray systems

Industrial instrumentation

PLC analog I/O modules

Field transmitters
