GENERAL DESCRIPTION
The ADP2140CPZ-RedyKit™ allows simplified prototyping and
evaluation and is available for every standard fixed output voltage
option in the ADP2140 product family. This allows the user to
evaluate the voltage options with one easy-to-order kit.
All surface-mount ADP2140 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 1).
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 ADP2140CPZ-RedyKit is available with 3.3 V buck and
1.8 V LDO and 1.8 V buck and 1.2 V LDO 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).
