INTRODUCTION
linear power amplifiers circuits using the PA50/PA52 pin out.
With ample breadboarding areas it is flexible enough to analyze
a multitude of standard or proprietary circuit configurations.
Critical connections for power supply bypassing are pre-wired.
Components not usually readily available in engineering labs
are provided. External connection to the evaluation kit can be
made via the terminal block and terminal pads at the edges of
the circuit board. The terminal pads are suitable for soldering
standard banana jacks or direct soldering of wires. The schematic
is shown in Figure 2.
BEFORE YOU GET STARTED
* All Apex Precision Power amplifiers should be handled using
* Do not change connections while the circuit is powered.
* Initially set all power supplies to the minimum operating volt-
