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 VDD. When in shutdown mode, the amplifier

output is in a high impedance state. The SHDN pin must never be left floating, but tied to

VCC or VDD.

The turn-on and turn-off time are calculated for an output variation of ±200 mV (Figure 18

and Figure 19 show the test configurations).
