R/2R Ladder Networks
R/2R Ladder Networks are available in both DIP and SIP
(Molded or Conformal) configurations.
taken from the R/2R ladder. This terminal (OUT) is commonly
used to drive an operational amplifier. R (the terminating resis-
T
tor) is always connected to ground.

Standard R/2R Ladder Networks have a resistance tolerance of
±2.0% (±1.0% available on all but low profile SIPs).

The R/2R Ladder Network is commonly used for Digital to
Analog (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
