REF70 Ultra-High-Precision Voltage Reference with Low Noise and Low Drift

1 Features

3 Description

•

Low noise :

The REF70 device family offers a unique combination

of very low noise (0.22 ppm_p-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.

– 1/f Noise (0.1 Hz to 10 Hz): 0.22 ppm_p-p

– 10 Hz to 1 kHz: 0.5 ppm_rms

Low temperature drift coefficient :

– 2 ppm/°C (maximum for -40°C to 125°C)

High accuracy: ±0.025% (maximum)

Available in humidity resistance ceramic package

(LCCC)

Low dropout: 250 mV

Wide input voltage: 3 V to 18 V

Output current: ±10 mA

•

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.

Industry standard voltage options: 2.5 V, 3.0 V, 3.3

V, 4.096 V, 5.0 V

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

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.
