Features nn Guaranteed ± 4m V Initial Accuracy LT1004-1.2 nn Guaranteed ±20m V Accuracy LT1004-2.5 nn Guaranteed 10µA Operating Current nn Guaranteed Temperature Performance nn Operates up to 20m A nn Very Low Dynamic Impedance Applications nn Portable Meter References nn Portable Test Instruments nn Battery-Operated Systems nn Current Loop Instrumentation LT1004 Micropower Voltage Reference Description The LT®1004 micropower voltage reference is a 2-terminal bandgap reference diode designed to provide high accuracy and excellent temperature characteristics at very low operating currents. Optimization of the key parameters in the design, processing and testing of the device results in accuracy specifications previously attainable only with selected units. Below is a distribution plot of reference voltage for a typical lot of LT1004-1.2. Virtually all of the units fall well within the prescribed limits of ±4m V. The LT1004 is a pin-for-pin replacement for the LM185/LM385 series of...
