such as DDC s RDC- 190/S and RD-1930 require closely matched Vrms sin/cos input voltages to minimize digital error.

Most resistor networks are matched to 0.0%, which equates to 1 LSB of error for a 16-bit application.

THIN-FILM RESISTOR NETWORKS FEATURES High Reliability Precision Tolerance Lead Free Available DESCRIPTION Synchro/Resolver-to-Digital converters such as DDC s RDC- 190/S and RD-1930 require closely matched Vrms sin/cos input voltages to minimize digital error. DDC offers custom thin-film resistor networks that provide precision matched Vrms outputs for Vrms, 11.8 Vrms, or 90 Vrms applications. Most resistor networks are matched to 0.0%, which equates to 1 LSB of error for a 16-bit application. APPLICATIONS These thin-film resistor networks are ideal for use with monolithic Synchro/Resolver-to-Digital converters that require Vrms sin/cos inputs. 105 Wilbur Place Bohemia, New York Fax: FOR MORE INFORMATION CONTACT: Technical Support: DDC-5757 ext All trademarks are the property of their respective owners. 003

R1 tolerance specification is 0.1% of 70.8k and an actual value measured must be used for the relative values. value (1k) must be offset to be relative to R1. Example: R1 (70.8K) actually measured = K = (Within 0.1% spec) is relative to R1 required = 1K Offset calculation is as follows: = Relative resistor actual value x (Resistor value to be calculated / Relative resistor value) = K x (1K / 70.8K) = 1.006K installed must be 1.006k +/- 0.0% Next relative value to calculate is R4 (Note that the data sheet listing is in alpha order, not working order) R4 (70.8K) is relative to R1 R1 (70.8K) actually measured = K R4 required = 70.8K R4 Offset calculation is as follows: R4 = Relative resistor actual value x (Resistor value to be calculated / Relative resistor value) R4 = K x (70.8K / 70.8K) = K R4 installed must be K +/- 0.0% Next relative value to calculate is, which is relative to R4. R4 must be measured for calculation offset must be calculated Installed must be within 0.0% of calculated offset value. 3
