The TRF1108 is a very high-performance, differential-to-single-ended (D2S) amplifier optimized for radio-frequency (RF) applications. The device is an excellent choice for applications that require a D2S conversion at the output of digital-to-analog converter (DAC) such as the high-performance DAC39RF10 or AFE7950. The on-chip matching components simplify printed-circuit-board (PCB) implementation and provide the highest performance over the usable bandwidth. The device is fabricated using Texas Instruments’ advanced complementary BiCMOS process and is available in a space-saving, WQFN-FCRLF 2mm × 2mm package.
The primary use-case of the TRF1108 is in ac-coupled applications, where the device operates using a single, 5V supply with an internally set common-mode voltage that simplifies biasing. With the help of an application circuit to set the input common-mode voltage, and by using dual supplies, the amplifier can be dc-coupled. A power-down feature is also available for power savings.
