Product Details

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. Figure 1 and Figure 2 in the user guide 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 the user guide when using the EVAL-ADA4351-2EBZ.
