Description
DDC converters such as the RDC-19220/2S and RD-19230 require closely matched 2Vrms
Sin/Cos input voltages to minimize 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 percent-
ages. The networks are matched to 0.02%, which equates to 1LSB of error for a 16-bit
application.
