REF5040AIDGKR Description

The REF5040AIDGKR from Texas Instruments is a high-precision, low-noise 4.096V series voltage reference designed for applications requiring exceptional accuracy and stability. Housed in an 8-pin VSSOP package, this fixed-output reference delivers ±0.1% initial tolerance and an ultra-low 8ppm/°C temperature coefficient, ensuring minimal drift over temperature variations. With a 12µVpp/V noise performance (0.1Hz to 10Hz), it excels in noise-sensitive systems. Operating from 4.296V to 18V input, it consumes only 1.2mA supply current while providing 10mA output current, making it suitable for power-constrained designs. Compliant with ROHS3 and REACH, it is ideal for industrial, medical, and test equipment applications.
