SPX1004 - Precision Voltage Reference
DESCRIPTION The SPX1004 is a 2-terminal high precision bandgap voltage reference that provides a stable 1.2V and 2.5V fixed output voltage with a tolerance of ±4mV for the SPX1004- 1.2 and ±20mV for the SPX1004- 2.5. Design, process and yield cut the chip with a very low temperature accuracy factor of 25 ppm/°C. The SPX1004 can be used as a pin-to-pin replacement for the LT1004, LM1004 or AS1004. The SPX1004 is available in SOT-89 and SOIC-8 and TO-92 packages over the operating temperature range of 0°C to 70°C
Features ■Initial Voltage Tolerance:
SPX1004- 1.2= ±4mV
