LT1355/LT1356 Dual and Quad 12MHz, 400V/s Op Amps FEATURES DESCRIPTION n 12MHz Gain Bandwidth The LT 1355/LT1356 are dual and quad low power high n 400V/s Slew Rate speed operational amplifiers with outstanding AC and DC n 1.25mA Maximum Supply Current per Amplifier performance. The amplifiers feature much lower supply n Unity-Gain Stable current and higher slew rate than devices with comparable n C-Load Op Amp Drives All Capacitive Loads bandwidth. The circuit topology is a voltage feedback n 10nV/Hz Input Noise Voltage amplifier with matched high impedance inputs and the n 800V Maximum Input Offset Voltage slewing performance of a current feedback amplifier. The n 300nA Maximum Input Bias Current high slew rate and single stage design provide excellent n 70nA Maximum Input Offset Current settling characteristics which make the circuit an ideal n 12V/mV Minimum DC Gain, R = 1k choice for data acquisition systems. Each output drives a L n 230ns Settling Time to 0.1%, 10V Step 500 load to 12V with 15V supplies and a 150 load to n 280ns Settling Time to 0.01%, 10V Step 2.75V on 5V supplies. The amplifiers are stable with any n 12V Minimum Output Swing into 500 capacitive load making them useful in buffer applications. n 2.75V Minimum Output Swing into 150 The LT1355/LT1356 are members of a family of fast, high n Specified at 2.5V, 5V, and 15V performance amplifiers using this unique topology and employing Linear Technology Corporations advanced bipolar complementary processing. For a single amplifier APPLICATIONS version of the LT1355/LT1356 see the LT1354 data sheet. n Wideband Amplifiers For higher bandwidth devices with higher supply currents n Buffers see the LT1357 through LT1365 data sheets. Bandwidths n Active Filters of 25MHz, 50MHz, and 70MHz are available with 2mA, n Data Acquisition Systems 4mA, and 6mA of supply current per amplifier. Singles, n Photodiode Amplifiers duals, and quads of each amplifier are available. L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
