The 10M resistor, adds a 1 LSB ‘‘thump’’, to  
allow full offset binary operation where the out-  
put reaches zero for the half-scale code. If  
symmetrical output excursions are required,  
omit the 10M resistor.

a) Switch all the digital inputs high; adjust the V potenti-

ometer of op amp B to bring its output to a value equal  
Assuming that the external 10k resistors are matched to  
better than 0.1%, the gain adjust of the circuit is the same  
with the one previously discussed.
