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
taken from the R/2R ladder. This terminal (OUT) is commonly
used to drive an operational amplifier. RT (the terminating resis-
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).

How To Order R/2R Ladder Networks
41 16 R - R2R - 503
Resistance/Capacitance Code
(For value of R). 2R is double this value.
• First 2 digits are significant.
• Third digit represents the number
of zeros to follow.
Electrical Configuration
• R2R = R/2R Ladder Network
