Operational Amplifier
DESCRIPTION
The LT^®1351 is a low power, high speed, high slew rate
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 1kΩ load to
±13V with ±15V supplies and a 500Ω load to ±3.4V on ±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.
