The LT

operational amplifier with outstanding AC and DC perfor-

mance. The LT1351 features lower supply current, lower

input offset voltage, lower input bias current and higher

DC gain 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 en-

sures that the large-signal bandwidth is not degraded. The

amplifier is a single gain stage with outstanding settling

characteristics which make the circuit an ideal choice for

data acquisition systems. The output drives a 1k

Ω load to

±13Vwith ±15Vsuppliesanda500Ωloadto ±3.4Von ±5V

supplies. The amplifier is also stable with any capacitive

load which makes it useful in buffer or cable driver

applications.

The LT1351 is a member of a family of fast, high perfor-

mance amplifiers using this unique topology and employ-

ing Linear Technology Corporation’s advanced

complementary bipolar processing. For dual and quad

amplifier versions of the LT1351 see the LT1352/LT1353

data sheet. For higher bandwidth devices with higher

supply current see the LT1354 through LT1365 data sheets.

Singles, duals and quads of each amplifier are available.
