Note: Do not attempt to scale for higher output voltages by inputting a reference voltage above the
maximum specified voltage.
*S4 is active only in Resolver mode.
4.1.3
Scaling Lower Output Voltages
The output voltages can be scaled down by lowering the reference input voltage as
follows:
Reference Input Voltage = Desired Output Voltage / TR
Example:
Desired Output Voltage = 10 Vrms
TR = 0.4538
Reference Input Voltage = 10 Vrms / 0.4538
Reference Input Voltage = 22 Vrms

Two Speed
Two speed allows resolutions greater than 16 bits to be achieved. Refer to the Two-
Speed Application Note (
AN/MFT-10
), the RD/RDC Applications Manual (
MN-
19220XX-001
) and the Synchro/Resolver Conversion Handbook. These documents

Self Test
The device has a built-in self test capability which uses an internal DC reference to
exercise all channels and indicates a pass or fail status for each channel. This
