FS7755. The supply voltage should be maintained at 5V ± 5% for specified operation.
This pin should be decoupled with a 10μF capacitor in parallel with a ceramic 100nF
capacitor.
FS7755. The supply should be maintained at 5V ± 5% for specified operation. Every
effort should be made to minimize power supply ripple and noise at this pin by the use of
proper decoupling. This pin should be decoupled to AGND with a 10μF capacitor in
parallel with a ceramic 100nF capacitor.
voltage inputs with a maximum differential signal level of ±470mV for specified
operation. Channel 1 also has a PGA, and the gain selections are outlined in Table
The maximum signal level at these pins is ±1V with respect to AGND. Both inputs have
internal ESD protection circuitry. An overvoltage of ±6V can be sustained on these
inputs without risk of permanent damage.
fully differential input pair. The maximum differential input voltage is ±660mV for
specified operation. The maximum signal level at these pins is ±1V with respect to
AGND. Both inputs have internal ESD protection circuitry, and an over-voltage of ±6V
can also be sustained on these inputs without risk of permanent damage.
