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.
