2 Current Generation of Texas Instruments Isolated Amplifiers Radiated Emissions Performance

The isolated amplifiers from Texas Instruments such as the AMC1300B-Q1, AMC1300, AMC1302, and AMC1311 incorporate several years of radiated emissions EMI performance advancements, including, but not limited to: an optimized analog signal chain, the amount of energy crossing over the isolation barrier was more closely managed, and OOK data transmission. As shown in Figure 2-1, these devices have excellent radiated emissions EMI performance, with only a few high frequency radiated emissions visible above the noise floor of the chamber. These high-frequency emissions are visible around 820 Mhz with 20 dB of margin and extends to 980 MHz with 16 dB of margin.
