3 Description

The TRF1208 is a very high performance, RF

Amplifier optimized for radio frequency (RF)

applications. This device is ideal for ac-coupled

applications that require a single-ended to differential

conversion when driving an analog-to-digital

converter (ADC) such as the high performance

ADC12DJ5200RF. The on-chip matching components

simplify printed circuit board (PCB) implementation

and provide the highest performance over the

usable bandwidth. The device is fabricated in Texas

Instruments’ advanced complementary BiCMOS

process and is available in a space-saving, WQFNFCRLF

package.

It operates on a single-rail supply and consumes

about 138 mA of active current. A power-down feature

is also available for power savings.
