rdc19220 ETC-unknow, rdc19220 Datasheet - Page 22

• Manufacturer Part Number: rdc19220
• Description: 16-bit Monolithic Tracking Resolver Lvdt -to-digital Converters
• Manufacturer: ETC-unknow

Note 1: The lead-free option is available with a Matte Tin finish. DDC can provide the reliability
and tin whisker growth data associated with these products ; however, tin whisker growth is
dependent on the application enviornment and customers should collect their own reliability data
and perform a risk assesment based on their individual requirements.
Note 2: DDC does not recommend Tape and Reel due to potential lead damage.
Note 3: Solder DIP is not available on the MQFP package.
Description
DDC converters such as the RDC-19220 series 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 resis-
tor networks have very low imbalance percentages. The networks are matched to 0.02%, which equates to 1LSB of error for a 16-bit
application.
