LT6274/LT6275
90MHz, 2200V/µs
30V Low Power Op Amps
FEATURES
DESCRIPTION
The LT®6274/LT6275 are single/dual low power, high
speed, very high slew rate operational amplifiers with
outstanding AC and DC performance. The circuit topology
is a voltage feedback amplifier with matched high imped-
ance inputs plus the enhanced slewing performance of a
current feedback amplifier. The high slew rate and single
stage design provide excellent settling characteristics that
make the circuit an ideal choice for data acquisition sys-
tems. Each output drives a 1k load to ±1ꢀ.25ꢁ with ±15ꢁ
supplies and a 500Ω load to ±ꢀ.5ꢁ on ±5ꢁ supplies. The
LT6274/LT6275 are stable with any capacitive load mak-
ing them useful in buffer or cable driving applications.
