3 Description

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, highspeed,

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.
