The devices are functionally equivalent to the EL16V devices with an input that control the amplitude of the outputs. The operational range of the EL16VS control input is from VBB (max. swing) to VCC (min. swing). Simple control of the output swing can be obtained by a variable resistor between the VBB pin and VCC with the wiper driving VCTRL. The EL16VS provides a VBB output for either singleended use or as a DC bias for AC coupling to the device. The VBB pin should be used only as a bias for the EL16VS as its current sink/source capability is limited. Whenever used, the VBB pin should be bypassed to ground via a 0.01µF capacitor. Under open input conditions (pulled to VEE), internal input clamps will force the Q output LOW.
