The Texas Instruments REF3440QDBVRQ1 is a high-performance, automotive-qualified series voltage reference designed for demanding applications. It provides a stable and accurate voltage output with a low temperature coefficient of 6 ppm/°C and an initial accuracy of ±0.05% maximum.
This voltage reference operates over a wide input voltage range of 2.55 V to 12 V and can supply an output current of up to ±10 mA. It features a low quiescent current of typically 72 µA, making it suitable for power-sensitive designs. The REF3440QDBVRQ1 also boasts low output 1/f noise (3.8 µVPP/V) and excellent long-term stability of 25 ppm/1000 hrs.
Available in SOT-23 and VSSOP packages, this device is designed for surface mount applications. Its AEC-Q100 qualification ensures reliability in automotive environments, with a temperature grade of 1 (-40°C to +125°C).
Key electrical characteristics include multiple output voltage options (2.5V, 3.0V, 3.3V, 4.096V, 5.0V), a low shutdown current of 2.5 µA typical, and functional safety capabilities.
