Operation of the SuprAmpA requires only the connection of power, control signals,
motor and limit switches.
In normal operation, the input signal is buffered by the power op-amp at unity gain. A
+/- 10 Volt signal input will yield +/- 10 Volts drive to the load.
Optional limit switch protection
When the limit switch inputs are not at ground, operation is unaffected. When the
positive limit switch signal is grounded, the inputs to the op-amp are shorted only if the
polarity of the input signal is positive. Likewise, when the negative limit switch signal is
grounded, the inputs to the op-amp are shorted only if the polarity of the input signal is
negative. This allows the controller to provide a reverse polarity to move the stage away
from the inhibiting switch, but does not otherwise affect operation.
Please note that the op-amp short is isolated from the input pins by 10K ohms.
Because of the active limit switch circuitry, the op-amp supply voltage is limited to 18
Volts. If operation at higher voltages is desired, the limit switch circuitry must be removed or
supplied separately. When the limit switch circuitry is removed or protected, the power
supply input for the amplifier may be increased to +/- 35 Volts.
