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.
