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 sup-
ply current and higher slew rate than devices with compa-
rable bandwidth. The circuit combines the slewing perfor-
mance 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 1k
load to
13V with
15V supplies and a 500
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.

Note 1: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefinitely.
Note 2: 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 3: Full-power bandwidth is calculated from the slew rate
measurement: FPBW = (Slew Rate)/2
V
P
.
Note 4: This parameter is not 100% tested.
Note 5: The LT1352/LT1353 are designed, characterized and expected to
meet these extended temperature limits, but are not tested at 40
C and
85
C. Guaranteed I grade parts are available, consult factory.
