LT1031/LH0070 UCROSS REFERENCE The following cross reference guide may be used to select CROSS REFERENCE GUIDE/LT1031 TO AD581 LT1031 grades which meet or exceed output voltage, AD581J order LT1031DCH temperature drift, load and line regulation, and output AD581K order LT1031CCH current specifications of the AD581 reference. Parameters AD581L order LT1031BCH such as noise, hysteresis, and long term stability will be A0581S order LT1031DMH significantly better for all LT1031 grades compared to the A0581U order LT1031BMH AD581.
