THS6212 - Texas Instruments

THS6212 Differential Broadband PLC Line Driver Amplifier

The THS6212 is a differential line-driver amplifier with a current-feedback architecture. The device is targeted for use in broadband, wideband power line communications (PLC) line driver applications and is fast enough to support transmissions of 14.5-dBm line power up to 30 MHz. The unique architecture of the THS6212 uses minimal quiescent current and st.
