The LTC6228/LTC6229 are single/dual very fast, low noise rail-to-rail output, unity gain stable op amps. They have a gain-bandwidth product of 890MHz and a slew rate of 500V/μs. The low input referred voltage noise of only 0.88nV/√Hz and low distortion performance of better than −100dB at 4VP-P even for signals as fast as 2MHz 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 combination of low offset, low offset drift, high gain and high CMRR make the LTC6228 family the superior choice for wide dynamic range applications.

The LTC6228 family maintains excellent performance for supply voltages of 2.8V to 11.75V and the devices are specified at supplies of 3V, 5V and 10V(±5V). 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.

For space constrained PCB layouts, the LTC6228 is available in a 2mm × 2mm DFN and the LTC6229 is available in a 3mm × 3mm DFN. The amplifiers are also available in conventional leaded packages. These amplifiers can be used as improved replacements for many high speed op amps to improve speed, noise, distortion and dynamic range.

Applications

  • Optical Electronics: Fast Transimpedance Amplifiers
  • Driving High Dynamic Range A/D Converters
  • Active Filters
  • Video Amplifiers
  • High Speed Differential to Single-Ended Conversion
  • Low Voltage Hi-Fi Amplification

Evaluating the LTC6226 and the LTC6228 Low Distortion, Rail-to-Rail Output Op Amps with Shutdown

Features and Benefits

  • Enables efficient prototyping
  • User defined circuit configuration
  • Edge mounted SMA connector provisions
  • Simple connection to test equipment and other circuits
  • RoHS compliant 

Product Detail

The EVAL-LTC6226S8/EVAL-LTC6228IS8 allow the evaluation of the LTC6226 and the LTC6228, 8-lead, single channel, small outline integrated circuit (SOIC_N), 150 mil op amps. The EVAL-LTC6226S8 and EVAL-LTC6228IS8 are prepopulated boards on a buffer configuration with a post low-pass filter. This configuration allows the LTC6226 and the LTC6228 to be used as a high speed analog-to-digital converter (ADC) drivers. The EVAL-LTC6226S8/EVAL-LTC6228IS8 support other typical configurations of an op amp and have provisions for typical applications of the LTC6226 and the LTC6228, which include an active filter. The SHDN_N pin can be shunt to the VCC pin or the VEE pin, or to an external voltage drive.

The 4-layer EVAL-LTC6226S8/EVAL-LTC6228IS8 accept 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-LTC6226S8/EVAL-LTC6228IS8 have 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-LTC6226S8/EVAL-LTC6228IS8 accept 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-LTC6226S8/EVAL-LTC6228IS8, and no components are placed on the secondary side. The EVAL-LTC6226S8 and EVAL-LTC6228IS8 evaluation boards are identical except for the on-board devices.

For full details on the LTC6226 and the LTC6228, see the LTC6226 and the LTC6228 data sheets, which must be consulted in conjunction with the user guide when using the EVAL-LTC6226S8/EVAL-LTC6228IS8.
