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). Standard R/2R Ladder Networks Availability is as follows: DIP/SMD SIP-CONFORMAL SIP MOLDED 14 Pin - 7 Bit 6 Pin - 4 Bit 6 Pin - 4 Bit 16 Pin - 8 Bit 7 Pin - 5 Bit 8 Pin - 6 Bit 8 Pin - 6 Bit 10 Pin - 8 Bit 9 Pin - 7 Bit 10 Pin - 8 Bit 11 Pin - 9 Bit 12 Pin -10 Bit 14 Pin -12 Bit Resistor Power Ratings @ 70˚ C Low Profile SIP & DIP .................................................... .125W Medium Profile SIP ........................................................ .170W High Profile SIP .............................................................. .200W How To Order R/2R Ladder Networks 41 16 R - R2R - 503 Model Resistance/Capacitance Code (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 (46 = Conformal SIP) of zeros to follow. (48 = SMD) Number of Pins Physical Configuration Electrical Configuration (R = Low Profile - Molded) • R2R = R/2R Ladder Network (X = Low Profile - Conformal) (M = Medium Profile) (H = High Profile) (P = Medium Body SOIC) R/2R Ladder Networks |
