SBOS487B June 2009 – March 2020 PGA280
Amplifiers vary in susceptibility to electromagnetic interference (EMI), but good layout practices play a critical role. EMI can generally be identified as a variation in offset voltage shifts. The PGA280 has been specifically designed to minimize susceptibility to EMI by incorporating an internal low-pass filter. Additional EMI filters may be required next to the signal inputs of the system, as well as known good practices such as using short traces, low-pass filters, and damping resistors combined with parallel and shielded signal routing, depending on the end system requirements.
