Product Number:  LTC2621  

    		        		    		    

		    		    
		    			

			    
Hello, I am trying to do an accuracy analysis on this part and I was wondering if the following can be provided: 


    

  1. Offset Error Drift
    2. 

  2. Reference Temperature Coefficient (TC)
    3. 

  3. The tolerance on the Vref of Vcc=5V
    4.

    Hi  ,
    

    1. Offset Error Drift
    -> The datasheet doesn't exactly provide the offset drift but if it can suffice your analysis, the Offset Error and Temperature coefficient are available.
    2. Reference Temperature Coefficient
    -> The LTC2621 only uses external reference so this spec will depend on the reference used.
    3.     The tolerance on the Vref of Vcc=5V
    -> You can safely use Vref in this range: 0V ≤ VREF ≤ VCC. The tolerance will depend on the stability of the rail and reference used as both of these are external supplies.
    

    Hope this helps.

    Flynn
