SPX1004

SPX1004 1.2V / 2.5V Micropower Voltage Reference FEATURES ■ Initial Voltage Tolerance: SPX1004-1.2 = ±10mV SPX1004-2.5 = ±20mV ■ Low Dynamic Impedance 0.6 Ω Max. ■ Low Operating Current: SPX1004-1.2 = ±10µA SPX1004-2.5 ±20µA ■ Wide Operating Current Range 0.6 Ω Max. ■ Direct Replacement for LT1004, LM1004 and AS1004 ■ Lead Free, RoHS Compliant Packages N/C 1 N/C 2 N/C 3 ANODE 4 SPX1004 8 Pin NSOIC 8 CATHODE 7 N/C 6 CATHODE 5 ANODE APPLICATIONS ■ A/D and D/A Reference ■ Reference for 5V Systems ■ Digital Voltmeter ■ Power Supply Monitor 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. The SPX1004 can be used as a pin-to-pin replacement for the LT1004, LM1004 or AS1004. The SPX1004 is available in SOT-89, NSOIC-8 and TO-92 packages over the operating temperature range of 0°C to 70°C.
