DESCRIPTIO
The LT®6301 is a 500mA minimum output current, quad
op amp with outstanding distortion performance. The
amplifiers are gain-of-ten stable, but can be easily com-
pensated for lower gains. The extended output swing al-
lows 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 imped-
ance inputs with low input bias current and input offset
voltage. Active termination is easily implemented for fur-
ther system power reduction. Short-circuit protection and
thermal shutdown ensure the device’s ruggedness.
The outputs drive a 100load 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.

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 LT6301C 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
LT6301I 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, 14, 15, 28 and the exposed bottom side metal 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: Matching is between amplifiers A and B or between amplifiers
C and D.
Note 7: RBIAS is connected between V + and each SHDN pin, with each
SHDNREF pin grounded.
Note 8: Channel separation is measured between amplifiers A and B and
between amplifiers C and D. Channel separation between any other
combination of amplifiers is guaranteed by design as two separate die are
used in the package.
Note 9: 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.
