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.

Evaluation Kits (1)
The EVAL-LTC6228IS8 allows the evaluation of the LTC6228, 8-lead, single channel, small outline integrated circuit (SOIC-N), 150 mil operational amplifier (op amp). The EVAL-LTC6228IS8 is a prepopulated board on a buffer configuration with a post low-pass filter at a cutoff frequency of 80 MHz. This configuration allows the LTC6228 to be used as a high speed analog-to-digital converter (ADC) driver. The EVAL-LTC6228IS8 supports other typical configurations of an op amp and has provisions for typical applications of the LTC6228, which includes an active filter. The SHDN_N pin can be shunt with the VCC pin, the VEE pin, or to an external voltage drive.
The 4-layer EVAL-LTC6228IS8 accepts edge mounted Subminiature Version A (SMA) connectors on both inputs and outputs to provide an efficient connection to the test equipment and other circuitry. In addition, the EVAL-LTC6228IS8 has sufficient test points for signal pins and groundings.
Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The EVAL-LTC6228IS8 accepts C0402 or C0603 surface-mount technology (SMT) components and C1206 bypass capacitors for C8 and C9.
All components are placed on the primary side of the EVAL-LTC6228IS8, and no components are placed on the secondary side.
For full details on the LTC6228, see the LTC6228 data sheet, which must be consulted in conjunction with this user guide when using the EVAL-LTC6228IS8.
