Product Details

The LTC6227 are very fast, low noise rail-to-rail output, unity gain stable single/dual op amps, with a gainbandwidth 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 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.
