LT1352/LT1353
Dual and Quad
250µA, 3MHz, 200V/µs
Operational Amplifiers
DESCRIPTIO
The LT
®
1352/LT1353 are dual and quad, very low power,
high speed operational amplifiers with outstanding AC
and DC performance. The amplifiers feature much lower
supply current and higher slew rate than devices with
comparable bandwidth. The circuit combines the slewing
performance of a current feedback amplifier in a true
operational amplifier with matched high impedance
inputs. The high slew rate ensures that the large-signal
bandwidth is not degraded. Each output is capable of
driving a 1kΩ load to
±13V
with
±15V
supplies and a 500Ω
load to
±3.4V
on
±5V
supplies.
The LT1352/LT1353 are members of a family of fast, high
performance amplifiers using this unique topology and
employing Linear Technology Corporation’s advanced
complementary bipolar processing. For higher bandwidth
devices with higher supply current see the LT1354 through
LT1365 data sheets. Bandwidths of 12MHz, 25MHz, 50MHz
and 70MHz are available with 1mA, 2mA, 4mA and 6mA of
supply current per amplifier. Singles, duals and quads of
each amplifier are available. The LT1352 is available in an
8-lead SO package. The LT1353 is offered in a 14-lead
narrow surface mount package.

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:
Slew rate is measured between
±8V
on the output with
±12V
input for
±15V
supplies and
±2V
on the output with
±3V
input for
±5V
supplies.
Note 5:
Full-power bandwidth is calculated from the slew rate
measurement: FPBW = (Slew Rate)/2πV
P
.
Note 6:
This parameter is not 100% tested.
Note 7:
The LT1352C/LT1353C are guaranteed to meet specified
performance from 0°C to 70°C. The LT1352C/LT1353C 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.
The LT1352I/LT1353I are guaranteed to meet specified performance
from – 40°C to 85°C.
