THS6043EVM Applications
3.7 Noninverting Single-Ended Gain Stages
Although ADSL is the obvious application for the THS6043EVM, it can also be
configured for other applications.There are component locations on the EVM
that allow various dc- and ac-coupled gain stages to be constructed.
Referring to Figure 3−7, for example, two dc-coupled noninverting gain stages
could be formed by:
- Removing R7 and C3
- Making R8 and R9 gain resistors for the two individual stages.
An ac-coupled gain stage for the top amplifier can be constructed by:
- Removing R7 and C3
- Making R8 and R9 gain resistors for the two individual stages.
- Using a dc blocking capacitor at locations Z1 and Z3
There are many possibilites—these suggestions are not meant to limit the
options of the user.
