Instrumentation amplifiers can be built with individual op-amps and precision resistors, but are also available in integrated circuit form from several manufacturers (including Texas Instruments, Analog Devices, Linear Technology and Maxim Integrated Products).
Instrumentationsforstærkere kan bygges af diskrete operationsforstærkere og precisionsresistorer, men er også tilgængelige som integrerede kredsløb fra adskillige producenter (inklusiv Texas Instruments, National Semiconductor, Analog Devices, Linear Technology og Maxim Integrated Products).
