The LT

op amp with outstanding distortion performance. The

amplifiers are gain-of-ten stable, but can be easily com-

pensated for lower gains. The extended output swing al-

lows for lower supply rails to reduce system power. Supply

current is set with an external resistor to optimize power

dissipation. The LT6301 features balanced, high imped-

ance inputs with low input bias current and input offset

voltage. Active termination is easily implemented for fur-

ther system power reduction. Short-circuit protection and

thermal shutdown ensure the device’s ruggedness.

The outputs drive a 100

Ω load to ±11.1V with ±12V

supplies, and

±10.9V with a 250mA load. The LT6301 is a

functional replacement for the LT1739 and LT1794 in

xDSL line driver applications and requires no circuit

changes.

The LT6301 is available in the very small, thermally

enhanced, 28-lead TSSOP package for maximum port

density in line driver applications.
