REF5025ID

REF5025ID Description

The REF5025ID from Texas Instruments is a high-precision, low-noise 2.5V series voltage reference designed for applications demanding exceptional accuracy and stability. Housed in an 8-SOIC package, this IC delivers ±0.05% initial tolerance and an ultra-low 3ppm/°C temperature coefficient, ensuring minimal drift over temperature variations. With a 7.5µVpp/V noise performance (0.1Hz to 10Hz), it is ideal for sensitive analog circuits. Operating from a 2.7V to 18V input range, it supports a 10mA output current while consuming only 1.2mA supply current, making it suitable for power-constrained systems. Compliant with ROHS3 and REACH standards, it is available in a tube packaging with MSL 2 (1 Year) moisture sensitivity.
