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.

BASIC OPERATION
The input SMA connector IN is terminated with a 49.9
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.
