SBOSAJ4 June 2024 TLV9304-Q1
PRODMIX
The TLV930x-Q1 uses integrated electromagnetic interference (EMI) filtering to reduce the effects of EMI from sources such as wireless communications and densely-populated boards with a mix of analog signal chain and digital components. EMI immunity can be improved with circuit design techniques; the TLV930x-Q1 benefits from these design improvements. Texas Instruments has developed the ability to accurately measure and quantify the immunity of an operational amplifier over a broad frequency spectrum extending from 10MHz to 6GHz. Figure 6-3 shows the results of this testing on the TLV930x-Q1. Table 6-1 shows the EMIRR IN+ values for the TLV930x-Q1 at particular frequencies commonly encountered in real-world applications. Table 6-1 lists applications that may be centered on or operated near the particular frequency shown. The EMI Rejection Ratio of Operational Amplifiers application note contains detailed information on the topic of EMIRR performance as it relates to operational amplifiers.
