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.
