General Information
1.6
Using the THS7001 EVM
The THS7001 EVM operates from a split power supply with voltages ranging
from
±
5 V to
±
15 V. It also uses 5 volt logic control signals to configure the
operation of the EVM when the DIP switches are used. The use of a single
supply for this EVM is not recommended. As shipped, the preamplifier is set
to a gain of 2 and the preamplifier directly drives the PGA stage. An
oscilloscope is typically used to view and analyze the EVM output signals.
1)
Ensure that all power supplies are set to
OFF
before making power supply
connections to the THS7001 EVM.
2)
Select the operating voltage for the EVM and connect appropriate split
power supplies to the banana jacks on the module marked
+V
CC
(J1) and
–V
CC
(J3).
3)
Connect a 5-V power supply to the banana jack marked
+5 V
(J4).
4)
Connect all power supply grounds to the banana jack marked
GND
(J2).
5)
Connect an oscilloscope probe to the PGA–A amplifier output BNC (J9).
Connecting directly to J9 with a 50-
nominal impedance cable and probe
is not recommended. The output drive capability of the PGA is very limited.
Such a connection will load the output excessively, reducing the output
voltage range of the amplifier and is not a true measurement of the
amplifier performance.
6)
Set EVM jumpers as shown in Table 1–3.

8)
Set the power supplies to
ON
.
9)
Connect a signal input to the
INPUT A
BNC (J6).
Note that each input connector on this EVM is terminated with a 50-
resistor
to ground. With a 50-
source impedance, the voltage seen by the THS7001
amplifier IC on the EVM will be the source signal voltage applied to the EVM
input connector.
10) Verify the output signal on the oscilloscope using a high-impedance probe
— a voltage gain of approximately 2.5 to 1 should be observed.
