    Thread Summary
    
                The user inquired about the correct resistance value for R22 and R23 in the DC1856B schematic, noting a discrepancy between the schematic (10 Ohms) and the dsn file (10K Ohms). The final answer confirms that both R22 and R23 should be 10 Ohms.

    Hi All
    

     In the schematic of DC1856B, R22 and R23 are 10ohm  but if you open the dsn file you see they are 10Kohm 0603.
    

    Can anybody valid the right value?
    

    from the Application note it is pobalby 10ohm
