SBOSAM3A July 2025 – August 2025 INA600
PRODMIX
The INA600 uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from a variety of sources. These sources include wireless communications and densely-populated boards with a mix of analog signal chain and digital components. Texas Instruments accurately measures and quantifies the immunity of an operational amplifier over a broad frequency spectrum extending from 10MHz to 6GHz. The EMI Rejection Ratio of Operational Amplifiers application note is available for download from www.ti.com. This application note contains detailed information on the topic of EMIRR performance relating to op amps.
Figure 7-2 shows the results of this testing on the INA600 for differential EMI interference. Figure 7-3 shows the results of this testing on the INA600 for common-mode EMI interference. Table 7-2 provides the EMIRR IN+ values for the INA600 at particular frequencies commonly encountered in real-world applications.
