Figure 87. Drive Circuit at High Input Frequencies
Using Differential Amplifier Drive Circuits
Figure 88 shows a drive circuit using a differential amplifier (TI's THS4509) to convert a single-ended input to
differential output that can be interface to the ADC analog input pins. In addition to the single-ended to differential
conversion, the amplifier also provides gain (10 dB). RFIL helps to isolate the amplifier outputs from the switching
input of the ADC. Together with CFIL it also forms a low-pass filter that band-limits the noise (and signal) at the
ADC input. As the amplifier output is ac-coupled, the common-mode voltage of the ADC input pins is set using
two 200-
resistors connected to VCM.
The amplifier output can also be dc-coupled. Using the output common-mode control of the THS4509, the ADC
input pins can be biased to 1.5 V. In this case, use +4-V and
–1-V supplies for the THS4509 so that its output
common-mode voltage (1.5 V) is at mid-supply.
