LTC6226/LTC6227 Rail-to-Rail Output Op Amps Analog Devices LTC6226/LTC6227 Rail-to-Rail Output Operational Amplifiers (Op Amps) are very fast, low noise, unity-gain stable single/dual op amps, with a gain-bandwidth product of 420MHz and a slew rate of 180V/μs. The low input-referred voltage noise of only 1nV/√Hz and low distortion of less than –90dBC for 4VP-P signals at 1MHz makes them ideal for applications that require high dynamic range and deal with very fast signals, such as driving A/D converters. The combination of low offset, low offset drift, high gain (139dB) and high CMRR (114dB) make these excellent devices for high dynamic range applications.
