Product description.
The SuprAmpA is a general-purpose operational power amplifier, which can be used for a
variety of applications. However, it has been optimized for use as a motor driver, with pin
connections to match products made by Physik Instrumente.
The SuprAmpA accepts an industry-standard +/- 10 Volt input to drive precision-size
motors bi-directionally. A Burr-Brown OPA541 power op-amp provides the amplification
function. As shipped, the gain is set at unity, but may be easily modified in the field by
changing the values of the gain-setting resistors.
A DB-25 connector (J1) provides connection for input signals, power supply and
operational signals returned from the motor connector. A DB-15 connector (J2) provides
direct connection to motor functions and passes through those that require service in other
assemblies. The passed through signal functions are noted for a Physik Instrumente
standard connector. The limit switches are passed through as well as actively used to
interrupt potentially dangerous drive conditions.
