LT1004 - Micropower Voltage Reference
DESCRIPTION The LT®1004 is a micropower voltage referenced bi-terminal bandgap reference diode designed to provide high accuracy and excellent temperature characteristics with very low operating current. The key to optimization lies in the design parameters, machining and testing of the equipment in the previous results to achieve the accuracy index of only selected units. Below is a distribution diagram of a typical lot of reference voltages for the LT1004-1.2. Almost all units are well below the specified limit, ±4mV.
The LT1004 is a pin-to-pin replacement for the LM185/LM385 family reference, which in turn improves accuracy specifications. What's more, the LT1004 is an attractive device for use in systems where the accuracy rate previously gained is in power consumption spending and trimming. For a guaranteed low drift reference temperature coefficient for micropower, see the LT1034 data sheet. ...
