Analog Devices Inc. LTC6228 High-Speed Operational Amplifiers
Analog Devices Inc. LTC6228 High-Speed Operational Amplifiers are low noise rail-to-rail output and unity gain stable op amps having a high slew rate of 500V/μs. These amplifiers are the perfect choice for wide dynamic range applications due to the combination of low offset, low offset drift, high CMRR, and high gain. The LTC6228 operational amplifiers consist of an input range extending to the negative rail and an output range that encompasses the entire supply range. This enables the LTC6228 amplifiers to accommodate wide swinging signals and single supply operation.
The LTC6228 operational amplifiers feature ultra-low voltage noise, low distortion at high speeds, and ability to enable/disable internal bias current cancellation to optimize noise performance. These amplifiers operate at -40°C to 125°C temperature range and are available in a 2mm x 2mm DFN package. The LTC6228 operational amplifiers are ideal for applications that require high dynamic range and deal with high slew rate signals. Typical applications include active filters, video amplifiers, fast trans-impedance amplifiers, and low voltage Hi-Fi amplification.
