Texas Instruments, however, has a zero drift chopping topology that is unique in the industry. Instead of the noisy odd order harmonics, TI designs incorporate a proprietary synchronous notch filter that attenuates the chopping noise inherent in the zero drift design and filters out the odd order harmonics. The result is that the chopping noise is reduced to far below the broadband noise of the amplifier. TI’s zero drift products achieve industry leading noise performance far outpacing competitor’s similar product offerings.
