Description

General part information

REF35409 Series

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.
