Texas Instruments THS6222 Differential Line-Driver Amplifier

The unique architecture of the THS6222 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 mid supply common-mode buffer eliminates external components, reducing system cost, and board space.

The wide output swing of 57VPP (100Ω load) with 32V power supplies, coupled with over 650mA current drive (25Ω load), allows for a wide dynamic range that keeps distortion minimal. The Texas Instruments THS6222 is available in a 24-pin VQFN package with an exposed thermal pad and is specified for operation from –40°C to +85°C ambient temperature.
