Description

      The R/2R is used widely, the following descriptions may help you know about the R/2R. The R/2R ladder networks are available in both DIP and SIP, whether it is molded or conformal configurations. The R/2R ladder network is commonly used for digital toanalog (D/A) conversions and analog to digital (A/D) conversion by successive approximations. The bits of the ladder are the points at which input signals are presented to the ladder and the output terminal (OUT) is the point at which the output is taken from the R/2R ladder. This terminal (OUT) is commonly used to drive an operational amplifier. RT (the terminating resistor) is always connected to ground. Standard R/2R ladder networks have a resistance tolerance of ±2.0% on the condition that it is ±1.0% available on all but low profile SIPs.
      You should also know how to order the R/2R ladder networks. For example the model is 4116R-2R-503. The 41 is model, there are also other model numbers. Such as 41 is molded DIP, 43 is molded SIP, 44 is wide body SMD, 46 is conformal SIP, and 48 is SMD. The 16 is number of pins, the R is physical configuration. There are also some other physical configurations, such as R is low profile molded, X is low profile conformal, M is medium profile, H is high profile, P is medium body SOIC. The R2R is electrical configuration, here you need to know R2R is R/2R ladder network. The 503 is resistance or capacitance code. I should tell you that for value of R, 2R is double this value. Here you ought to know two notes. On the one hand note is the first 2 digits are significant, on the other hand the third digit represents the number of zeros to follow.
      There three resistor power ratings of the R/2R. The first is low profile SIP & DIP, which is 125W. The second is medium profile SIP, which is 170W. The third is high profile SIP, which is 200W.
