The LT
®
6300 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 LT6300 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 ±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.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Applies to short circuits to ground only. A short circuit between
the output and either supply may permanently damage the part when
operated on supplies greater than ±10V.
Note 3: The LT6300C is guaranteed to meet specified performance from
0°C to 70°C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and 85°C. The
LT6300I is guaranteed to meet the extended temperature limits.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to Pins 1, 8, 9, 16 of the device. If the maximum
dissipation of the package is exceeded, the device will go into thermal
shutdown and be protected.
Note 5: Guaranteed by the CMRR tests.
Note 6: R
BIAS
is connected between V
+
and the SHDN pin, with the
SHDNREF pin grounded.
Note 7: Slew rate is measured at ±5V on a ±10V output signal while
operating on ±12V supplies and ±1V on a ±3V output signal while
operating on ±5V supplies.
