Evaluation Board
The performance of the HFA1405 PDIP or SOIC can be
evaluated using the HA5025 Evaluation Board. The
HFA1405IB (SOIC) requires a SOIC to DIP adaptor like the
Aries Electronics Part Number 14-350000-10.
The schematic for the PDIP/SOIC amplifier 1 and the
HA5025EVAL board layout are shown in Figure 2 and Figure
3. Resistors RF, RG, and +RS may require a change to
values applicable to the HFA1405.
To order evaluation board (part number HA5025EVAL), please
contact your local sales office.
