The REF35 is a family of nanopower, low-drift, high-precision 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 options.
