LTC6226/LTC6227 Hz 1nV/ 420MHz GBW, 180V/s, Low Distortion Rail-to-Rail Output Op Amps FEATURES DESCRIPTION n Ultra Low Voltage Noise: 1nV/Hz The LTC 6226/LTC6227 are very fast, low noise rail-to-rail n Low Distortion: HD2/HD3<90dB at 4V ,1MHz output, unity gain stable single/dual op amps, with a gain- C P-P into 1k bandwidth product of 420MHz and a slew rate of 180V/s. n High Slew Rate: 180V/s The low input referred voltage noise of only 1nV/Hz and n GBW = 420MHz low distortion of less than 90dB for 4V signals at C P-P n 3dB Frequency (A = +1): 330MHz 1MHz makes them ideal for applications that require high V n Input Common Mode Range Includes Negative Rail dynamic range and deal with very fast signals, such as n Output Swings Rail-to-Rail driving A/D converters. n Supply Current: 5.5mA/Channel Typ The combination of low offset, low offset drift, high gain n Operating Supply Range: 2.8V to 11.75V (139dB) and high CMRR (114dB) make these excellent n Input Offset Voltage: 95V Max devices for high dynamic range applications. n Offset Drift :0.4V/C n The LTC6226 family maintains excellent performance for Low Power Shutdown n supply voltages of 2.8V to 11.75V and the devices are fully Very High Open Loop Gain: 9V/V (139dB), R = 1k L n specified at supplies of 3V, 5V and 10V (5V). Operating Temp Range: 40C to 125C n Single in 8-Lead SOIC, TSOT-23, 2mm 2mm DFN. With an input range extending to the negative rail and Duals in 3mm 3mm DFN, MS8E rail-to-rail output stage, the operational amplifier can accommodate wide swinging signals, and true single APPLICATIONS supply operation. n Optical Electronics: Fast AC-Coupled Transimpedance For space constrained applications, the amplifiers come Amplifiers in 2mm 2mm DFN (single) and 3mm 3mm DFN n Driving High Dynamic Range A/D Converters (dual) packages. The devices are also available in 8-lead n Active Filters SOIC,TSOT-23 and MS8E. n Video Amplifiers These amplifiers can be used as replacements for many high n Low Voltage Low Distortion Amplification speed op amps to improve speed, noise and dynamic range.
