Product Details

The LT6301 is a 500mA minimum output current, quad 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 LT6301 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 ensure the device’s ruggedness.

The outputs drive a 100Ω 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.
