1.1
Description
The THS4500 EVM provides a platform for developing high-speed FDA
application circuits. It contains the THS4500 high-speed FDA, a number of
passive components, and various features and footprints that enable the user
to experiment, test, and verify various operational amplifier circuit
implementations. The PC board measures 3.08 by 2.42 inches.

Evaluation Module Features
THS4500 high-speed operational amplifier EVM features include:
Wide operating supply voltage range: single supply 5 Vdc to dual supply
±
5 Vdc operation (see the device data sheet). Single supply operation is
obtained by jumpering GND (J7) to
V
S
(J5).
Single-ended and fully differential input capability
Single-ended and fully differential output capability
Nominal 50-
input termination (R1||R2). Termination can be configured
according to the application requirement.
V
OCM
direct input through TP1
Power down (PD) direct input through TP2
Output transformer T1
Footprints for antialiasing filter implementation using locations R6, R7, C5,
and C6
Footprints for low pass filter implementation using locations C3, C4
800-
load provided through R8, R10, R9, and R11 reflected through T1
Three convenient GND test points on the PCB
Power supply ripple rejection capacitors (C8 and C11)
Decoupling capacitors (C9, C12) populated with 0.1
μ
F capacitors
design final decoupling in accordance with SLOA069
PowerPAD
heatsinking capability
A good example of high-speed amplifier PCB design and layout
