Power Amp Design manufactures power operational amplifiers (op amps) for industrial applications. Our products attain power levels not achievable by monolithic op amps but are as simple to use.  With an isolated metal substrate, integrated heat sink and fan cooling, our approach decreases weight and system complexity while increasing power density. The results are simple, high performance solutions for many power op amp applications. Most models are available without the heat sink and fan for custom applications. Our power op amp models are supported by evaluation (development) kits and optional accessory modules that add extra features and performance. SPICE models can be downloaded for your circuit simulator program. Expert application assistance is readily available as well.
