REF3440IDBVR Description

Short technical summary and product information.

The Texas Instruments REF3440IDBVR is a high-precision CMOS voltage reference designed for demanding applications. It features a low temperature drift of 6ppm/°C and an initial accuracy of ±0.05%. The device operates efficiently with low power consumption, drawing less than 95µA of quiescent current.

 

This voltage reference supports a wide input voltage range from 2.55V to 12V and can provide an output current of up to ±10mA. It exhibits low output noise of 12.5µVPP (0.1 to 10 Hz) and excellent long-term stability of 25ppm/1000hrs. The REF3440IDBVR is available in a compact 6-pin SOT-23 package, making it suitable for space-constrained designs.

 

Key electrical characteristics include an ultra-low zero load dropout voltage of 100mV (maximum). The device also features a 4-wire output and an enable pin for added control. Its operating temperature range is from -40°C to +125°C, ensuring reliable performance in various environmental conditions.
