LT1739  
Dual 500mA, 200MHz  
xDSL Line Driver Amplifier

FEATURES  
DESCRIPTIO  
TheLT®1739isa500mAminimumoutputcurrent,dualop  
amp with outstanding distortion performance. The ampli-  
fiersaregain-of-tenstable, butcanbeeasilycompensated  
for lower gains. The extended output swing allows for  
lowersupplyrailstoreducesystempower. Supplycurrent  
is set with an external resistor to optimize power dissipa-  
tion. The LT1739 features balanced, high impedance in-  
puts with low input bias current and input offset voltage.  
Active termination is easily implemented for further sys-  
tempowerreduction.Short-circuitprotectionandthermal  
shutdown insure the device’s ruggedness.  
3mm × 4mm High Power DFN Package  
Exceeds All Requirements For Full Rate,  
Downstream ADSL Line Drivers  
±500mA Minimum IOUT  
±11.1V Output Swing, VS = ±12V, RL = 100Ω  
±10.9V Output Swing, VS = ±12V, IL = 250mA  
Low Distortion: 82dBc at 1MHz, 2VP-P Into 50Ω  
Power Saving Adjustable Supply Current  
Power Enhanced TSSOP-20 Small Footprint Package  
200MHz Gain Bandwidth  
600V/µs Slew Rate  
Specified at ±12V and ±5V  
The outputs drive a 100load to ±11.1V with ±12V  
supplies, and ±10.9V with a 250mA load. The LT1739 is a  
pin-for-pin replacement for the LT1794 in xDSL line driver  
applications and requires no circuit changes.  
U
APPLICATIO S  
High Density ADSL Central Office Line Drivers  
The LT1739 is available in the very small, thermally  
enhanced, 3mm × 4mm DFN package or a 20-lead TSSOP  
for maximum port density in central office line driver  
applications. For a dual version of the LT1739, see the  
LT6301 data sheet.
