The LT

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 1k

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.
