Introduction

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.
