Application Notes
(Continued)
Figure 3
shows the output waveform.
If bipolar transistor power dissipation is not tolerable, the
switch could be by a N-channel enhancement mode MOS-
FET.
2.7V SINGLE SUPPLY 2:1 MUX
The schematic show in
Figure 4
will function as a 2:1 MUX
operating on a single 2.7V power supply, by utilizing the
shutdown feature of the LMV118.
Figure 5
shows the MUX output when selecting between a
1MHz sine and a 250kHz triangular waveform.
As can be seen in
Figure 5
, the output is well behaved and
there are no spikes or glitches due to the switching. Switch-
ing times are approximately around 500ns based on the time
when the output is considered “valid”.
