R/2R Ladder Networks R/2R Ladder Networks are available in both DIP and SIP (Molded or Conformal) configurations. OUT 16 16-PIN 8-BIT DIP RT 9 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% (±1.0% available on all but low profile SIPs). 15 14 13 12 11 10 R 2R 1 1 MSB 2 2 R 2R 3 3 R 2R 4 4 R 2R 5 5 R 2R 6 6 R 2R 7 7 R 2R 8 2R 2R Standard R/2R Ladder Networks Availability is as follows: DIP/SMD 14 Pin - 7 Bit 16 Pin - 8 Bit SIP-CONFORMAL 6 Pin - 4 Bit 7 Pin - 5 Bit 8 Pin - 6 Bit 9 Pin - 7 Bit 10 Pin - 8 Bit 11 Pin - 9 Bit 12 Pin -10 Bit 14 Pin -12 Bit SIP MOLDED 6 Pin - 4 Bit 8 Pin - 6 Bit 10 Pin - 8 Bit PIN BIT 8 LSB 10-PIN 8-BIT SIP R 2R 2 1 MSB 3 2 R 2R 4 3 R 2R 5 4 R 2R 6 5 R 2R 7 6 R 2R 8 7 R 2R 9 8 LSB 2R 10 RT 2R PIN 1 BIT OUT 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 Resistor Power Ratings @ 70˚ C Low Profile SIP & DIP ....................................................
