The R2R Ladder Network is used in Digital to Analog and
Analog to Digital conversion. Binary weighted currents,
flowing in the individual ladder segments, depend on the
integrity of the R:2R relationship for an accurate conversion
result. Fabricated with Tantalum Nitride on Silicon, these
resistors feature excellent stability, TCR and tracking
performance. R2R Ladder Networks are available in a range
of miniature packages conforming to JEDEC standards.
