Figure 1. Amplifier U2 produces a single-ended voltage output from the voltage across the bridge circuit. The circuit uses the popular Pt100 RTD, which has a resistance of 100 Ω at 0°C. Its ...

This is a 35W audio power amplifier built with TDA2030 in a bridged connection with a +- 15V symmetric PS. It is easy to build, do it yourself audio amplifier which will deliver up to 35W on a 8Ω ...
