Figure 4-6. Input Amplifiers with Sample and Hold Chips
SSH OUT is synchronized to the analog input boards S&H chip and the channel select MUX. When the analog input board samples channel 0, each of the LF398s on the CIO-SSH16 also samples the signal on its input. Each of the LF398s then switches to HOLD mode and the analog input board acquires this “held” signal from each channel. The CIO-SSH16 remains in HOLD mode until the analog input board samples channel 0 again.
