GENERAL DESCRIPTION
The EVAL-ADA4351-2EBZ evaluation board is designed to help
users evaluate the ADA4351-2, a two-channel programmable gain
transimpedance amplifier (PGTIA) that features an integrated gain
switching network with two user-defined gain states that can be set
via external resistors, offered in a 3 mm × 3mm × 0.78 mm, 16-lead
lead frame chip scale package (LFCSP).
The EVAL-ADA4351-2EBZ is a 4-layer printed circuit board (PCB)
with dimensions at 2.9 inches x 2.25 inches.

shows the top and bottom view of the EVAL-ADA4351-2EBZ,
respectively. The EVAL-ADA4351-2EBZ comes populated with
the key components that allow users to run and to evaluate
the board quickly and with relative ease. That aside, the EVAL-
ADA4351-2EBZ also provides open resistor and capacitor slots on
its input and output stages, allowing the user to install components

with user-defined values for connections such as a low-pass filter
(LPF) or voltage divider.
The EVAL-ADA4351-2EBZ is accessible through Subminiature
Version A (SMA) female socket edge mounts that allow users
to directly connect test equipment to the inputs and outputs of
both channels, as well as the gain switch control pins. The EVAL-
ADA4351-2EBZ also comes with an unpopulated photodiode slot
on each channel, allowing for quick prototyping.
For full details on the ADA4351-2, see the ADA4351-2 data sheet,
which should be consulted in conjunction with this user guide when
using the EVAL-ADA4351-2EBZ.
