3 Description
The REF35-Q1 is a family of nanopower, low-drift,
high-precision series reference devices. The REF35-
Q1 family features ±0.05 % initial accuracy with
typical 650 nA power consumption. The temperature
coefficient (15 ppm/ºC) and long-term stability (30
ppm 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 low
current applications.
The REF35-Q1 supplies up to 10 mA current with
3.3 ppmp-p noise and 20 ppm/mA load regulation.
With this feature set, REF35-Q1 creates a strong
low-noise, high accuracy power supply for precision
sensors and 12–16b data converters.
The family is fully specified for operation from -40°C to
125°C and is functional over -55°C to 125°C.
The REF35-Q1 is available in wide output voltage
variants starting from 1.20 V to 5.0 V. The device
is offered in space saving SOT23-6 pin package.
