Evaluation Board
The performance of the HFA1305IB (SOIC) may be
evaluated using the HA5025 Evaluation Board and a SOIC
to DIP adaptor like the Aries Electronics Part Number
14-350000-10.
The schematic for the 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 HFA1305IB.
To order evaluation board (part number HA5025EVAL),
please contact your local sales office.
