1.2 Description

The TI THS4031 high-speed operational amplifier evaluation module (EVM)

is a complete high-speed amplifier circuit. It consists of the TI THS4031

high-speed, low-power operational amplifier IC, along with a small number of

passive parts, mounted on a small circuit board measuring approximately

1.7 inch by 1.4 inch (Figure 1–1). The EVM uses standard SMA miniature RF

connectors for inputs and outputs and is completely assembled, fully tested,

and ready to use — just connect it to power, a signal source, and a load

(if desired).

The THS4031 EVM is equipped with both noninverting and inverting inputs.

The noninverting input is set for a gain of +2 and the inverting input is set for

a gain of –1. Each input is terminated with a 50-Ωresistor to provide correct

line impedance matching (Figure 1–2). The amplifier IC output is routed

through a 50-Ωresistor, both to provide correct line impedance matching and

to help isolate capacitive loading on the output of the amplifier. Capacitive

The gain of the EVM inputs can easily be changed to support a particular

application by simply changing the ratio of resistors R1, R4, and R5 as

described in the following equations:

)

In addition, some applications, such as those for video, may require the use

of 75-Ωcable and 75-ΩEVM input termination and output isolation resistors.

Any resistor on the EVM board can be replaced with a resistor of a different

value; however, care must be taken because the surface-mount solder pads

on the board are somewhat fragile and will not survive many desoldering/

soldering operations.

Notethatexternal factorscansignificantlyaffecttheeffectivegainoftheEVM.

For example, connecting test equipment with 50-Ωinput impedance to the

EVM output will divide the output signal level by a factor of 2 (assuming the

output isolation resistor on the EVM board remains 50 Ω). Similar effects can

occur at the input, depending upon how the input signal sources are

configured. The gain equations given above assume no signal loss in either

the input or the output.

The EVM circuit board is an excellent example of proper board layout for

high-speed amplifier designs and can be used as a guide for user application

board layouts.
