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).

(41 = Molded DIP)

(For value of R). 2R is double this value.

(43 = Molded SIP)

• First 2 digits are significant.

(44 = Wide Body SMD)

• Third digit represents the number
