TSH82 Configurable OpAmp Hookup Guide

The TSH82 Configurable OpAmp board was designed to give you the best combination of performance and flexibility that we could achieve. The TSH82 device itself has 2 gain stages, each one independently accessible via header. Each stage is natively configured as an inverting amplifier, giving you a gain of -4.7 with AC input coupling. Stringing both stages together gives you a gain of about 22. But with the use of the jumpers on the back of the board, you can additionally configure each stage for non-inverting operation, differential input, and DC input coupling. The board will also operate with a single-ended DC power supply of 4.5V to 12V, or a bipolar supply from +/-2.25V to +/-6V.
