PRODUCTION DATA
Multichannel amplifiers are often used to save space and cost. Proper printed circuit board (PCB) layout techniques can improve the crosstalk performance of multichannel amplifiers. The major cause of crosstalk is the capacitive coupling of the signal from one channel to the other. Following are some considerations to be taken into account to minimize the channel-to-channel crosstalk for a dual-channel THS4552:
Figure 9-4 shows the channel-to-channel crosstalk measurement for the THS4552 with a 2 VPP, single-ended sinusoidal input applied on one channel and crosstalk measured on other channel with G = 1 V/V on both channels.
