Figure 44. Simplified THS6032 Input Stages
Because the DGND pin voltage is effectively at a noninverting terminal, any signal or voltage fluctuation at this
node is amplified by the THS6032. This could possibly cause a noisy output to appear during shutdown
operation. Figure 45 shows the frequency response of the THS6032 due to an input signal at the DGND
terminal. The maximum DGND voltage signal which the THS6032 will follow linearly during shutdown operation
is less than
±
4 V. With this dynamic range capability, it is recommended that the DGND pin be as noise-free
as possible to ensure proper transmission line termination.
