Bulk Metal® Foil Technology
18 Pin Dual-In-Line Hermetic Resistor Network
The 18 pin “L” brazed DIP is still a 0.300" pin spacing package
butoverlapsthemountingholes,providingaddedchipcapacity.
It is a good choice for a 14 bit R/2R ladder of R = 5K. Select
Model 1460 for added chip area or additional pins. This
network can contain up to 80 V5X5 resistor chips.
