3 Description

The REF35 is a family of nanopower, low-drift, highprecision

series reference devices. The REF35 family

features ±0.05 initial accuracy with 650 nA typical

power consumption. The temperature coefficient (12

ppm/°C) and long-term stability (40 ppm at 1000

hours) of the device can help improve system stability

and reliability. The low power consumption combined

with high precision specifications are suitable for wide

variety of portable and low current applications.

The REF35 supplies up to 10 mA current with 3.3

ppmp-p noise and 20 ppm/mA load regulation. With

this feature set, REF35 creates a strong low-noise,

high accuracy power supply for precision sensors and

12–16b data converters.

The family is specified for operation from –40°C to

105°C and is functional over –55°C to 125°C. The

wide temperature is suited for industrial applications.

REF35 is available in wide output voltage variants

starting from 1.024 V to 5.0 V. The device is

offered in a space-saving, 6-pin SOT-23 and 4-pin

WCSP package options. Contact your local TI sales

representative for available voltage and package
