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 800µV 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, RL = 1k choice for data acquisition systems. Each output drives a n 230ns Settling Time to 0.1%, 10V Step 500Ω load to ±12V with ±15V supplies and a 150Ω 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 500Ω capacitive load making them useful in buffer applications. n ±2.75V Minimum Output Swing into 150Ω 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 Corporation’s advanced

bipolar complementary processing. For a single amplifier 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.
