650-nA quiescent current, 12-ppm/C drift, ultra-low-power precision voltage reference 6-SOT-23 -40 to 125

Description for the REF35

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.
