The amplifiers feature much lower supplycurrent and higher slew rate than devices with comparablebandwidth. The circuit topology is a voltage feedbackamplifier with matched high impedance inputs and theslewing performance of a current feedback amplifier . Thehigh slew rate and single stage design provide excellentsettling characteristics which make the circuit an idealchoice for data acquisition systems.

2 Each output drives a500 load to 13V with 15V supplies and a 150 load to on 5V supplies. The amplifiers are stable with anycapacitive load making them useful in buffer or cabledriving LT1361 /LT1362 are members of a family of fast, highperformance amplifiers using this unique topology andemploying Linear Technology Corporation s advancedbipolar complementary processing. For a single amplifierversion of the LT1361 /LT1362 see the LT1360 data higher bandwidth devices with higher supply currentssee the LT1363 through LT1365 data sheets.
