4.4 Shutdown function (TSV630)
The operational amplifier is enabled when the SHDN pin is pulled high. To disable the
amplifier, the
SHDN 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 must be
tied to V
CC+
or V
CC-
.
The turn-on and turn-off time are calculated for an output variation of ±200 mV (Figure 19
and Figure 20 show the test configurations).
Figure 21 and Figure 22 show the amplifier output voltage behavior when the SHDN pin is
toggled high and low.
