reflected in the Absolute Maximum Ratings table.
All pins on the VCA810 are internally protected from
ESD by means of a pair of back-to-back,
reverse-biased diodes to either power supply, as
shown in Figure 49. These diodes begin to conduct
when the pin voltage exceeds either power supply by
about 0.7V. This situation can occur with loss of the
amplifier power supplies while a signal source is still
