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 impedance 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 systems. 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 making them useful in buffer or cable driving applications.
