DESCRIPTION

Synchro/Resolver-to-Digital converters such as DDC’s RDC-

19220/2S and RD-19230 require closely matched 2 Vrms sin/cos

input voltages to minimize digital error. DDC offers custom thin-film

resistor networks that provide precision matched 2 Vrms outputs for

2 Vrms, 11.8 Vrms, or 90 Vrms applications. Most resistor networks

are matched to 0.02%, 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 2 Vrms sin/cos

inputs.

Notes for Table 1:

Understanding Table 1 relative %

Using DDC-49530 thin film as the example:

“R2” Relative to “R1” means the ratio of R2 to R1 is critical and must be main-

tained to .02%.

R1 tolerance specification is 0.1% of 70.8k and an actual value measured must

be used for the relative values.

“R2” value (12k) must be offset to be relative to R1.

Example:

R1 (70.8K) actually measured = 70.8354K = (Within 0.1% spec)

R2 is relative to R1

R2 required = 12K

R2 Offset calculation is as follows:

R2 = Relative resistor actual value x (Resistor value to be calculated / Relative

resistor value)

R2 = 70.8354K x (12K / 70.8K) = 12.006K

R2 installed must be 12.006k +/- 0.02%

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 = 70.8354K

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 = 70.8354K x (70.8K / 70.8K) = 70.8354K

R4 installed must be 70.8354K +/- 0.02%

Next relative value to calculate is R3, which is relative to R4.

R4 must be measured for calculation

R3 offset must be calculated

Installed R3 must be within 0.02% of calculated offset value.
