Figure 40. Using the THS4304 With the ADS5424
Besides these, Texas Instruments offers a wide
selection of single-ended operational amplifiers
(including the THS3201, THS3202 and OPA847) that
can be selected depending on the application. An RF
gain block amplifier, such as Texas Instrument鈥檚
THS9001, can also be used with an RF transformer for
high input frequency applications. For applications
requiring dc-coupling with the signal source, instead of
using a topology with three single ended amplifiers, a
differential input/differential output amplifier like the
THS4509 (see Figure 41) can be used, which
minimizes board space and reduce number of
components.
Figure 43 shows their combined SNR and SFDR
performance versus frequency with 鈭? dBFS input
signal level and sampling at 80MSPS.
On this configuration, the THS4509 amplifier circuit
provides 10 dB of gain, converts the single-ended input
to differential, and sets the proper input common-mode
voltage to the ADS5424.
The 225
鈩?/div>
resistors and 2.7 pF capacitor between the
THS4509 outputs and ADS5424 inputs (along with the
input capacitance of the ADC) limit the bandwidth of the
signal to about 100 MHz (鈭? dB).
For this test, an Agilent signal generator is used for the
signal source. The generator is an ac-coupled 50
鈩?/div>
source. A band-pass filter is inserted in series with the
input to reduce harmonics and noise from the signal
source.
Input termination is accomplished via the 69.8
鈩?/div>
resistor and 0.22
碌F
capacitor to ground in conjunction
with the input impedance of the amplifier circuit. A
0.22
碌F
capacitor and 49.9
鈩?/div>
resistor is inserted to
ground across the 69.8
鈩?/div>
resistor and 0.22
碌F
capacitor
on the alternate input to balance the circuit.
Gain is a function of the source impedance, termination,
and 348
鈩?/div>
feedback resistor. See the THS4509 data
sheet for further component values to set proper 50
鈩?/div>
termination for other common gains.
Since
the
ADS5424
recommended
input
common-mode voltage is +2.4 V, the THS4509 is
operated from a single power supply input with V
S+

+5 V and V
S鈭?/div>
= 0 V (ground). This maintains maximum
headroom on the internal transistors of the THS4509.
