MSOP-8EVM and MSOP-8EVM-PDK

Figure 1. MSOP-8EVM (Left) and MSOP-8EVM-PDK (Right)

This user's guide describes the characteristics, operation, and use of the MSOP-8EVM, both by itself and
as part of the MSOP-8EVM-PDK. This EVM is an evaluation board for single-channel, 14- to 16-bit,
analog-to-digital converter (ADC) devices in an MSOP-8 package. A complete circuit description,
schematic diagram, and bill of materials are included with this document.

This manual covers the operation of both the MSOP-8EVM and the MSOP-8EVM-PDK. It does not
describe the MMB0 motherboard in detail. Throughout this document, the abbreviation

EVM

and the term

evaluation module

are synonymous with the MSOP-8EVM.
