LT1004 - Micropower Voltage Reference
The LT1004 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 4mV.
The LT1004 is a pin-for-pin replacement for the LM 51b 185/LM385 series of references with improved accuracy specifications. More important, the LT1004 is an attractive device for use in systems where accuracy was previously obtained at the expense of power consumption and trimming.
For a low drift micropower reference with guaranteed temperature coefficient, see the LT1034 data sheet.
