LT6300

LT6300 500mA, 200MHz xDSL Line Driver in 16-Lead SSOP Package FEATURES s s s s s s s s s s DESCRIPTIO Exceeds All Requirements For Full Rate, Downstream ADSL Line Drivers Power Enhanced 16-Lead SSOP Package Power Saving Adjustable Supply Current ± 500mA Minimum IOUT ± 10.9V Output Swing, VS = ± 12V, RL = 100Ω ±10.7V Output Swing, VS = ± 12V, IL = 250mA Low Distortion: – 82dBc at 1MHz, 2VP-P Into 50Ω 200MHz Gain Bandwidth 600V/µs Slew Rate Specified at ±12V and ± 5V The LT®6300 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 LT6300 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 ±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. , LTC and LT are registere...
