Notes:
1) Resistors selected to limit Vref peak to between 1.5 V and 4 V.
2) External reference LO is grounded, then R3 and R4 are not
needed, and -R is connected to GND.
3) 10k ohms, 1 % series current limit resistors are recommended.
See Note 3.
Note: Five external BW components
as shown in Figures 1 and 2
are necessary for the R/D to
function.

R1 + R2 should not load the Resolver too much; it is recommended that R2 = 10k.
R1 + R2 Ratio Errors will result in Angular Errors,
2 cycle, 0.1% Ratio Error = 0.029 Peak Error.
Note: Five external BW components
as shown in Figures 1 and 2
are necessary for the R/D to
function.
