Analog Devices Inc. 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.

The LTC6226/LTC6227 family maintains excellent performance for supply voltages of 2.8V to 11.75V and the devices are fully specified at supplies of 3V, 5V, and 10V (±5V). With an input range extending to the negative rail and rail-to-rail output stage, the operational amplifier can accommodate wide-swinging signals and true single-supply operation. For space-constrained applications, the amplifiers come in 2mm × 2mm DFN (single) and 3mm × 3mm DFN (dual) packages. The devices are also available in 8-lead SOIC, TSOT-23, and MS8E. These amplifiers can be used as replacements for many high-speed op amps to improve speed, noise, and dynamic range.
