NOTES FOR FIGURES 1, 2, AND 3:
1. The "Sin FIB" and the "Cos FIB" pins of the SPA1695
should be connected directly of the "Sin" and "Cos"
terminals on the output transformer
at tbe transformer.
This is to compensate for any drop in voltage along the
connections between the "Sin O/P" and "Cos 0 IP" pins
of the amplifier and the transformer.

--

2. The "+ISY" and "-ISY" pins of the SPA169S should be
connected to a regulated power supply in order to drive
the internal operational amplifiers. The "+ISY(P)" and
"-ISY(P)" are used for the output stage and these supplies
need not be a precision source, the range of voltage when
considering all tolerances including ripple, should be be-
tween 14.7 S and 20 volts.
3. The part of the 0 volt system local to the amplifier and
converter should be tapped from the "GND(SIG)" pin on
the transformer and should not interconnect wi th any
other part of the 0 volt system by any other method (see
above diagram).

The 3 wire output signal is then monitored on an Angle
Position Indicator (e.g. APIl620 or AP11718) with no load
attached. A resistor R 1 should be connected across S 1 and S 3
until the API reads 45.00°.
A balanced load is then connected across S I, S2 and S3 the
change in angle is monitored by the API and minimized by
adding resistors (R2 and R3) in series with SI and S3. R2 and
R3 will have equal values. Increasing R2 and R3 will decrease
the angle monitored by the API.
Suggested initial values for R 1 is 27kn and for R2 and R3 is
30n.
