DESCRIPTION
The SPX1004 is a 2-terminal bandgap precision voltage reference that provides a stable fixed output voltage of 1.2V and 2.5V with a tolerance of ±10mV for SPX1004-1.2 and ±20mV for SPX1004-2.5. Design, process and precision on chip trimming yield a very low temperature coefficient of 25 ppm/°C.

FEATURES
■ Initial Voltage Tolerance:
    SPX1004-1.2 = ±10mV
