3 Description

The TRF1208-EP is a very high-performance

fully differential amplifier (FDA) optimized for

radio-frequency (RF) applications. This device is

an excellent choice for ac-coupled applications

that require single-ended-to-differential conversion

when driving an analog-to-digital converter (ADC)

such as the high-performance AFE7950-EP

or ADC12DJ5200-EP. 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,

WQFN-FCRLF package.

The TRF1208-EP operates on a single-rail supply and

consumes approximately 138mA of active current. A

power-down feature is available for power saving.
