REF1004I-2.5

REF1004 1.2V and 2.5V Micropower VOLTAGE REFERENCE FEATURES q INITIAL ACCURACY: REF1004-1.2 ±4mV REF1004-2.5 ±20mV q MINIMUM OPERATING CURRENT: REF1004-1.2 10µA REF1004-2.5 20µA q EXCELLENT LONG TERM TEMPERATURE STABILITY q VERY LOW DYNAMIC IMPEDANCE q OPERATES UP TO 20mA q PACKAGE: 8-Lead SOIC DESCRIPTION The REF1004-1.2 and REF1004-2.5 are two terminal bandgap reference diodes designed for high accuracy with outstanding temperature characteristics at low operating currents. Prior to the introduction of the REF1004 Micropower Voltage References, accuracy and stability specifications could only be attained by expensive screening of standard devices. The REF1004 is a cost effective solution when reference voltage accuracy, low power, and long term temperature stability are required. REF1004 is a drop-in replacement for the LT1004 as well as an upgraded replacement of the LM185/385 series references. The REF1004C is characterized for operation from 0°C to 70°C and the REF1004I is characterized for operation from –40°C to +85°C. The REF1004 is offered in an 8-lead Plastic SOIC package and shipped in anti-static rails or tape and reel.
