6 / 10 page 6 Evaluation Board The performance of the HFA1212 may be evaluated using the HA5023 Evaluation Board, slightly modified as follows: 1. Remove the two feedback resistors, and leave the con- nections open. 2. a. For AV = +1 evaluation, remove the gain setting resistors (R1), and leave pins 2 and 6 floating. b. For AV = +2, replace the gain setting resistors (R1) with 0 Ω resistors to GND. 3. Replace the 0 Ω series output resistors with 50Ω. The modified schematic for amplifier 1, and the board layout are shown in Figures 2 and 3. To order evaluation boards (part number HA5023EVAL), please contact your local sales office. −5V 10 µF 0.1 µF 50 Ω GND GND R 1 +5V 0.1 µF 10 µF 50 Ω IN OUT ∞ (A V =+1) or 0 Ω (AV =+2) NOTE: R1 = FIGURE 2.
