RESOLVER
INPUT
Note: Five external BW components
as shown in Figures 1 and 2
are necessary for the R/D to
function.
S1 and S3, S2 and S4, and RH and RL should be ideally twisted shielded,
with the shield tied to AGND at the converter.
For DDC-49530: Ri = 70.8 k
, 11.8 V input, synchro or resolver.
For DDC-49590: Ri = 270 k
, 90 V input, synchro or resolver.
Maximum addition error is 1 LSB.
