The LT

amp with outstanding distortion performance. The ampli-

fiers are gain-of-ten stable, but can be easily compensated

for lower gains. The extended output swing allows for

lower supply rails to reduce system power. Supply current

is set with an external resistor to optimize power dissipa-

tion. The LT6300 features balanced, high impedance in-

puts with low input bias current and input offset voltage.

Active termination is easily implemented for further sys-

tem power reduction. Short-circuit protection and thermal

shutdown insure the device’s ruggedness.

The outputs drive a 100

Ω load to ±10.9V with ±12V

supplies, and

±10.7V with a 250mA load. The LT6300 is a

functional replacement for the LT1739 and LT1794 in

xDSL line driver applications and requires no circuit

changes.

The LT6300 is available in the very small, thermally

enhanced, 16-lead SSOP package (same PCB area as the

SO-8 package) for maximum port density in line driver

applications.
