The LT

1794 is a 500mA minimum output current, dual op

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 LT1794 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 100Ω load to

±11.1V

with

±12V

supplies, and

±10.9V

with a 250mA load. The LT1794,

with its increased swing on lower supplies, can be used to

upgrade LT1795 line driver applications.

The LT1794 is available in the very small, thermally

enhanced, 20-lead TSSOP for maximum port density in

line driver applications. The 20-lead SW is also available.
