Description

TheLTC6228/LTC6229 are single/dual very fast, low noise rail-to-rail output, unity gain stable op amps. They have a gain-bandwidth product of 890MHz and a slew rate of 500V/μs. The low input referred voltage noise of only 0.88nV/√Hzand low distortion performance of better than −100dB at 4VP-Peven for signals as fast as 2MHz make them ideal for applications that require high dynamic range and deal with high slew rate signals, such as driving A/D converters. Additional features include Shutdown and the ability to enable/disable internal bias current cancellation to optimize noise performance.The combination of low offset, low offset drift, high gain and high CMRR make the LTC6228 family the superior choice for wide dynamic range applications.The LTC6228 family maintains excellent performance for supply voltages of 2.8V to 11.75V and the devices are specified at supplies of 3V, 5V and 10V(±5V). With an input range extending to the negative rail and an output range that encompasses the entire supply range, the operational amplifier can accommodate wide swinging signals, and single supply operation.For space constrained PCB layouts, the LTC6228 is available in a 2mm × 2mm DFN and the LTC6229 is available in a 3mm × 3mm DFN. The amplifiers are also available in conventional leaded packages. These amplifiers can be used as improved replacements for many high speed op amps to improve speed, noise, distortion and dynamic range.ApplicationsOptical Electronics: Fast Transimpedance AmplifiersDriving High Dynamic Range A/D ConvertersActive FiltersVideo AmplifiersHigh Speed Differential to Single-Ended ConversionLow Voltage Hi-Fi Amplification
