DESCRIPTIO
The LT1364/LT1365 are dual and quad high speed opera-
tional amplifiers with outstanding AC and DC perfor-
mance. The amplifiers feature much lower supply current
and higher slew rate than devices with comparable band-
width. The circuit topology is a voltage feedback amplifier
with matched high impedance inputs and the slewing
performance of a current feedback amplifier. The high
slew rate and single stage design provide excellent settling
characteristics which make the circuit an ideal choice for
data acquisition systems. Each output drives a 150Ω load
to ±7.5V with ±15V supplies and to ±3.4V on ±5V sup-
plies. The amplifiers are stable with any capacitive load
making them useful in buffer or cable driving applications.
The LT1364/LT1365 are members of a family of fast, high
performance amplifiers using this unique topology and
employing Linear Technology Corporation’s advanced
bipolar complementary processing. For a single amplifier
version of the LT1364/LT1365 see the LT1363 data sheet.
For 50MHz devices with 4mA supply currents see the
LT1360 through LT1362 data sheets. For lower supply
current amplifiers see the LT1354 to LT1359 data sheets.
Singles, duals, and quads of each amplifier are available.

Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Differential inputs of ±10V are appropriate for transient operation
only, such as during slewing. Large, sustained differential inputs will cause
excessive power dissipation and may damage the part. See Input
Considerations in the Applications Information section of this data sheet
for more details.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.
Note 5: Slew rate is measured between ±10V on the output with ±6V input
for ±15V supplies and ±1V on the output with ±1.75V input for ±5V supplies.
Note 6: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πVP.
Note 7: This parameter is not 100% tested.
Note 8: The LT1364C/LT1365C are guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 9: The LT1364C/LT1365C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1364C/LT1365C are designed,
characterized and expected to meet specified performance from – 40°C to
85°C, but are not tested or QA sampled at these temperatures. For
guaranteed I-grade parts, consult the factory.
