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.
