DESCRIPTION
The LTe1355/LT1356CS are dual and quad low power high speed operational amplifiers with outstanding AC and DC performance.The amplifiers feature much lower supply currentand higher slew rate than devices with comparable bandwidth.The circuit topology is a voltage feedbackamplifier with matched high impedance inputs and the slewing performance of a current feedback amplifier.The high slew rate and single stage design provide excellentsettling characteristics which make the circuit an idealchoice for data acquisition systems.Each output drives a 5002load to ±12V with±15V supplies and a 1502 load to ±2.75Von±5V supplies.The amplifiers are stable with any capacitive load making them useful in buffer applications.
The LT1355/LT1356CS are members of a family of fast, high performance amplifiers using this unique topology and employing Linear Technology Corporation's advanced bipolar complementary processing. For a single amplifierversion of the LT1355/LT1356CS see the LT1354 data sheet.
For higher bandwidth devices with higher supply currents see the LT1357 through LT1365 data sheets. Bandwidths of 25MHz,50MHz, and 70MHz are available with 2mA, 4mA, and 6mA of supply current per amplifier. Singles, duals, and quads of each amplifier are available.
