Texas Instruments (TI) has introduced what it says is the industry's first Class H VDSL line driver. Compared to Class AB alternatives, the gated, dual-port THS6226 consumes 47 percent less power, according to the company. By offering a digitally adjustable quiescent current (7.6 mA to 23.5 mA with a current step of 1 mA) the THS6226 line driver also allows for power savings while still achieving high linearity and low distortion. The part simplifies product sourcing and design by covering all VDSL profiles with a single line driver.
TI offers a variety of free tools and support to speed development with the THS6226, including a SPICE-based simulation program for designing, testing, and troubleshooting a broad variety of basic and advanced circuits, and Software for application and calculation utilities, including an active filter design application and a fully differential amplifier component calculator.
The THS6226 VDSL line driver is available now in a 5-mm x 5-mm QFN package, priced at $1.50 in quantities of 1,000.
