EVALUATION BOARD HARDWARE

The ADMV8052-EVALZ has the ADMV8052 chip on board.
The ADMV8052-EVALZ also includes a negative voltage
generator and three LDO regulators to provide the necessary
supply voltages for the chip. The regulators can be entirely
powered by the 5 V USB supply voltage from the PC via the
SDP-S.
To power the ADMV8052-EVALZ using the 5 V USB supply, slide
the S1 switch down (as shown in Figure 2) to power the on-board
negative voltage generator and LDO regulators. Alternatively, the
ADMV8052-EVALZ can be powered externally by sliding the S1
switch up and then connecting the power supplies to the VPOS
and VNEG Subminiature Version A (SMA) ports or test points.
The applicable voltage range for the positive input VPOS is
between 3.5 V and 5.5 V, and the applicable voltage range for
the negative input VNEG is between −5.5 V and −2.7 V.

Figure 2 shows an example lab bench setup for the ADMV8052-
EVALZ. To observe the filter response from the ADMV8052-
EVALZ, connect the RF1 and RF2 ports to a network analyzer
(or similar instrument). Typically, RF1 and RF2 are connected
to Port 1 and Port 2 on the network analyzer, as shown in
Figure 2.
