The LT1794ISW is a 500mA minimum output current, dual op amp with outstanding distortion performance. The amplifiers 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 dissipation. The LT1794ISW features balanced, high impedance inputs with low input bias current and input offset voltage. Active termination is easily implemented for further system 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 LT1794ISW 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.
