The THS6232 is a differential line-driver amplifier with current-feedback architecture, and provides high output current with low distortion performance. The device is targeted for use in broadband, high-speed, power-line communications (HPLC) line-driver applications that require high linearity when driving heavy line loads.
The unique architecture of the THS6232 uses minimal quiescent current while achieving very high linearity. The amplifier has an adjustable current pin (IADJ) that sets the nominal current consumption, along with the multiple bias modes that allow for enhanced power savings where the full performance of the amplifier is not required. Shutdown bias mode provides further power savings during receive mode in time division multiplexed (TDM) systems while maintaining high output impedance. The integrated midsupply common-mode buffer eliminates external components, reducing system cost and board space.
The wide output swing of 21VPP (100Ω load) with 12V power supplies, coupled with over 550mA of current drive, allows for wide dynamic range with minimal distortion.
The THS6232 is available in 24-pin VQFN package with exposed thermal pad, and is specified for operation from –40°C to +125°C.
