Amplifier Boards

This document provides technical specifications and operational guidelines for the A-series amplifier boards, specifically models A990 and A992. It includes detailed information on:

• Mounting: Requirements for commercial operational amplifiers, including gain, trim, and feedback network accommodations.
• Power: Electrical configuration details (positive at pin D, negative at pin E).
• Trimming: Setup instructions for wirewound potentiometers to allow for precise gain adjustment and the use of gain rheostats.
• Compatibility: A reference table outlining compatible amplifier devices from various manufacturers, such as Analog Devices, Burr-Brown, Data Device Corp., and others.
• Application Circuits: A series of schematic diagrams for various configurations including voltage followers, inverting/non-inverting amplifiers, integrators, summers, and subtractors.
