3.4 Shutdown function (TSV620)
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the SHDN
pin must be pulled down to V
CC-
. When in shutdown mode, the amplifier
output is in a high impedance state. The SHDN
pin must never be left floating but tied to
V
CC+
or V
CC-
.
The turn-on and turn-off times are calculated for an output variation of
±200 mV (Figure 16
and Figure 17 show the test configurations).
