4.7 Shutdown function
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 21
and Figure 22 show the test configurations. Figure 23 and Figure 24 show the respective
results with these test configurations.
