GENERAL DESCRIPTION 08404-001 The ADP2504CPZ-REDYKIT allows simplified prototyping and evaluation and is available for every standard fixed output voltage option in the ADP2504 product family. The kit allows the user to evaluate the voltage options with one easy to order kit. Figure 1. ADP2504CPZ-REDYKIT All surface-mount ADP2504 parts come sorted and stored in the kit with the Analog Devices, Inc., part number and fixed output voltage clearly printed on each zip-top bag (see Figure 5). The kit can be used in the engineering lab to evaluate required voltage options. If other voltage options must be evaluated, a different part from the kit can be easily soldered onto one of the evaluation boards supplied with the kit. The ADP2504CPZ-REDYKIT is available with fixed 2.8 V and 5.0 V evaluation boards. The kit also contains additional parts for prototyping. The kit enclosure, which contains individually packaged parts and the two evaluation boards, is packaged in an ESD foam pad inside a treated cardboard box that measures 8.7" (L) × 7.9" (W) × 1.75"(H), that is, 22 cm (L) × 20 cm (W) × 4.5 cm (H). The ADP2504 evaluation board data sheet, EVAL-ADP2503/ ADP2504, can be found at www.analog.com. RedyKit is a trademark of Analog Devices, Inc.
