LTC6228/9 Low Distortion Rail-to-Rail Output Op Amp with Shutdown

Analog Devices' LTC6228/9 are single/dual very fast, low-noise rail-to-rail output, unity-gain stable op amps

Image of Analog Devices' LTC6228 Low Distortion Rail-to-Rail Output Op Amp with ShutdownAnalog Devices' are single/dual very fast, low noise rail-to-rail output, unity gain stable op amps. They have a gain-bandwidth product of 890 MHz and a slew rate of 500 V/μs. The low input referred voltage noise of only 0.88 nV/√Hz and low distortion performance of better than −100 dB at 4 VP-P even for large signals as fast as 2 MHz make them ideal for applications that require high dynamic range and deal with high slew rate signals, such as driving A/D converters. Additional features include shutdown and the ability to enable/disable internal bias current cancellation to optimize noise performance.

The LTC6228 family maintains excellent performance for supply voltages of 2.8 V to 11.75 V and the devices are specified at supplies of 3 V, 5 V and 10 V(±5 V). With an input range extending to the negative rail and an output range that encompasses the entire supply range, the operational amplifier can accommodate wide swinging signals, and single supply operation.
