DESCRIPTION
The LT
廬
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鈩?load to
鹵13V
with
鹵15V
supplies and a 500鈩?load to
鹵3.4V
on
鹵5V
supplies.
The LT1352/LT1353 are members of a family of fast, high
performance amplifiers using this unique topology and
employing Linear Technology Corporation鈥檚 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.
