Amplifier Boards Types A990, A992

Summary This document provides technical specifications and application guidance for the A990 and A992 Series amplifier boards. These boards are designed to host various commercially available operational amplifiers by offering pre-drilled holes for component mounting and etched circuits for feedback and trimming networks.

Key details include:

• Power Requirements: Standardizes power connections at pin D (positive) and pin E (negative).
• Trimming: Includes provisions for mounting wirewound potentiometers to allow for precise gain adjustment and gain trimming.
• Compatibility: A table is provided listing various manufacturers (such as Analog Devices, Philbrick, and Zeltex) and the specific amplifier models compatible with the A990 and A992 boards.
• Circuit Configurations: The second page illustrates how these boards can be configured for a variety of functions, including voltage followers, inverting/non-inverting amplifiers, integrators, differentiators, four-input summers, and subtractors.
