Rev. 0 | 18 of 20

The RBIAS pin can be used as a fast enable and disable control

input. In the schematic in Figure 65, a single-pole, double throw

switch is used to switch the voltage on the RBIAS resistor between

0 V and 2.5 V. When the voltage on the RBIAS pin is equal to

response time of this circuit is shown in Figure 66.
