DESCRIPTION

90MHz, 2200V/µs

30V Low Power Op Amps

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 ±13.25V with ±15V

supplies and a 500Ω load to ±3.5V on ±5V supplies. The

LT6274/LT6275 are stable with any capacitive load mak-

ing them useful in buffer or cable driving applications.

The LT6274 single op amp is available in a 5-lead TSOT-23

package, and the LT6275 dual op amp is available in an

8-lead MSOP package. They operate with guaranteed

specifications over the –40°C to 85°C and –40°C to 125°C

temperature ranges.
