LT1351

DESCRIPTION

The LT ®1351 is a low power, high speed, high slew rate operational amplifier with outstanding AC and DC performance. 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 ensures 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 500Ωload 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.
