RD-19230
W-05/08-0
DDC converters such as the RDC-19220/2S and RD-19230
require closely matched 2Vrms SIN/COS input voltages to mini-
mize digital error. DDC has custom thin-film resistor networks
that provide the correctly matched 2Vrms converter outputs for
11.8Vrms Resolver/Synchro or 90Vrms synchro applications.
Any imbalance of the resistance ratio between the SIN/COS
inputs will create errors in the digital output. DDC’s custom thin-
film resistor networks have very low imbalance percentages. The
networks are matched to 0.02%, which equates to 1 LSB of error
for a 16-bit application.
