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
output is in a high impedance state. The SHDN pin must never be left floating but tied to
V
The turn-on and turn-off times are calculated for an output variation of ±200 mV
