Description
The TI THS7002 programmable-gain amplifier evaluation module (EVM) is a
complete dual-channel low-noise receiver and a highly configurable
programmable-gain amplifier circuit. It consists of the TI THS7002
Programmable-Gain Amplifier IC, a TI THS4001 high-speed, low-power
operational amplifier IC, and a number of passive parts, all mounted on a
multilayer circuit board (Figure 1–1).
Although the THS7002 IC was developed primarily for xDSL receiver
front-ends, there are a large number of different circuits that can benefit from
the many features incorporated into the THS7002. This EVM illustrates a
universal design and can be used for numerous system configurations.
The EVM uses standard BNC connectors for inputs and outputs and also
includes test points for user connections and testing. It is completely
assembled, fully tested, and ready to use — just connect it to power, a signal
source, and a load (if desired).
