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
