H | Page 29 of 32 EVALUATION BOARD GENERAL DESCRIPTION The AD8330-EVALZ is an easy-to-use accessory that enables a hands-on evaluation of the AD8330 variable gain amplifier (VGA). It includes test pins for connections to all of the functional device inputs. Figure 69 is a full size photograph of the board. Figure 69. Photograph of the AD8330 Evaluation Board BASIC OPERATION The input SMA connector IN is terminated with a 49.9 Ω resistor (see Figure 70). For convenience, the board includes an AD8131 high speed differential amplifier to convert a single- ended signal source to the differential input of the AD8330. If desired, the AD8131 can be removed and the AD8330 can be driven at one of its inputs from a single-ended source. The AD8330 output is observed at the SMA connectors OUT_HI and OUT_LO or by using the 2-pin header OUT_HI/OUT_LO adjacent to the device. The AD8330 requires only a +5 V power supply; however, because of the AD8131 buffer bipolar power supply requirements, ±5 V supplies are required to power the board. The current required for the board is approximately 40 mA from the +5 V supply and 10 mA from the −5 V supply. 8 7 2 3 9 GAIN_SLOPE C5 0.1µF C3 0.1µF INLO MODE VPSI INHI VPSO CMOP OPLO CNTR OFST OPHI 8 ENBL VPOS +5V 1 6 5 4 15 16 14 13 COMM VMAG VDBS CMGN 12 11 10 C2 0.1µF UP C18 0.1µF +5V C6 0.1µF IN +5V C7 0.1µF CMGN VDBS VMAG C10 0.1µF C19 0.1µF C11 0.1µF C4 0.1µF +5V C14 10nF C15 0.1µF CNTR ENBL 3 4 5 6 1 2 C16 10nF C20 0.1µF C17 10µF 10V –5V GND1 GND2 GND3 GND4 FLTR C9 12pF C8 12pF C12 0.1µF R4 0Ω R2 49.9Ω R1 24.9Ω OUT_HI OUT_ LO R3 1kΩ OUT_TEST IN_TEST C1 10µF 10V + OFST C13 1nF DOWN + A1 DUT1 AD8330 FILTER_OFFSET AD8131 Figure 70.
