Hardware and EVM Setup for Testing PGA5807A

This section outlines the external connections required for PGA5807A EVM as well as the default
configuration of the EVM’s 3-pin headers and 0-

Ω

jumper resistors with an explanation of configuration

options. The EVM is delivered with three unique signal path configurations available to the user with only
header changes required to the EVM. These configurations are PG ADS5296A (

PGA + ADC

),

PGA5807A only (

PGA Input/Output

), and ADS5296A only (

ADC Input

).

highlights which SMAs

are to be used for each configuration. (

Note: The PGA5807A output channels do not numerically match

the input channels of the ADS5296A, hence, there is a mapping from one to the other. The silkscreen
designators are named in such a way as to describe the mapping. For instance, the signal input to
channel 1 of the PGA5807A at SMA J10 will be captured on channel 5 at the output of the ADC, hence,
the designator name for SMA J10
