CONFIGURING THE ADA8282 THROUGH ACE

The ACE software provides several views or interfaces for configur-
ing the ADA8282 via the SDP-B. Raw SPI writes and reads may be
done through the register debugger. The chip view provides a more
graphical approach to configuring the ADA8282, while the memory
map provides users with the option to change register settings bit
by bit.

USING THE REGISTER DEBUGGER

Raw SPI data writes and reads may be performed on the device us-
ing the register debugger. The register debugger can be accessed
on ACE through the side bar under Tools.
To write to the device, complete the following steps:
1. Select the address from the Address drop-down menu on the
register debugger (see Figure
Figure 7. Register Debugger Drop-Down Menu
2. Enter the data to be written to the device in the Data text box
and click Write (see Figure

USING THE ACE SOFTWARE CHIP VIEW

The ACE software provides a chip view for the ADA8282. This al-
lows the user to configure the part graphically. Enabling or disabling
channels, along with gain manipulation, can be accomplished using
the chip view.
To enable or disable a channel, click the channel of interest. An
enabled channel is highlighted in blue, while a disabled channel is
grayed out. In Figure 10, Channel A is enabled, while the rest of the
channels are disabled.
Figure 10. Enabled and Disabled Channels
The ADA8282 gain is implemented using two internal gain stages.
The first stage is an LNA with a default gain of +24 dB, and the
second stage is a PGA with a gain that varies from −6 dB to +12
dB. To manipulate the total gain of a channel, select the desired
PGA gain on the PGA section as shown in
the gain of enabled channels may be changed (see
