The LT
6301 is a 500mA minimum output current, quad
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
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.
