EVAL-LTC6227MS8E/EVAL-LTC6229MS8E, Secondary Side GENERAL DESCRIPTION The EVAL-LTC6227MS8E/EVAL-LTC6229MS8E allow the LTC6227MS8E/EVAL-LTC6229MS8E have sufficient test evaluation of the LTC6227 and LTC6229, 8-lead, dual-channel, points for both signal pins and groundings. micro small outline package (MSOP) op amps. The EVAL- Optimized power and ground planes ensure low noise and high LTC6227MS8E and the EVAL-LTC6229MS8E are prepopulated speed operation. Component placement and power supply boards on a buffer configuration with a post low-pass filter. bypassing are optimized for maximum circuit flexibility and This configuration allows the LTC6227 and LTC6229 to be performance. The EVAL-LTC6227MS8E/EVAL-LTC6229MS8E used as high speed analog-to-digital converter (ADC) drivers. accept C0402 or C0603 surface-mount technology (SMT) The EVAL-LTC6227MS8E/EVAL-LTC6229MS8E support components and C1206 bypass capacitors for C5 and C6. other typical configurations of the op amps, and are configured All components are placed on the primary side of the EVAL- and have provisions for typical applications of the LTC6227 LTC6227MS8E/EVAL-LTC6229MS8E, and no components are and the LTC6229, including high speed, low voltage, low noise, placed on the secondary side. The EVAL-LTC6227MS8E and in-amp, and as an active filter. The exposed paddle pin is already EVAL-LTC6229MS8E evaluation boards are identical except shorted to the VEE turret pin, which is required for the device. for the on-board devices. The 4-layer EVAL-LTC6227MS8E/EVAL-LTC6229MS8E accept For full details on the LTC6227 and the LTC6229, see the LTC6227 edge mounted, Subminiature Version A (SMA) connectors on and the LTC6229 data sheets, which must be consulted in both inputs and outputs to provide an efficient connection to the conjunction with this user guide when using the EVAL- test equipment and other circuitry. In addition, the EVAL- LTC6227MS8E/EVAL-LTC6229MS8E. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. Rev.
