FEATURES
DESCRIPTION
The LT®1352/LT1353 are dual and quad, very low power,
highspeedoperationalamplifierswithoutstandingACand
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 1kΩ load to
±13V with ±15V supplies and a 500Ω load to ±3.4V on
±5V supplies.
