650-nA quiescent current, 12-ppm/°C drift, ultra-low-power precision voltage reference

The REF35 is a family of nanopower,

low-drift, high-precision series reference devices. The REF35 family features ±0.05% initial

accuracy with 650nA typical power consumption. The temperature coefficient (12ppm/°C) and

long-term stability (40ppm at 1000 hours) of the device can help improve system stability

and reliability. The low power consumption combined with high precision specifications are

designed for a wide variety of portable and low current applications.

The REF35 supplies up to 10mA current with

3.3ppmp-p noise and 20ppm/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 1.024V to 5.0V. 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 options.
