EVALUATION BOARD DESCRIPTION
The EVA L -AD2S1200/05SDZ is a full-featured evaluation board
designed to allow the user to easily evaluate all features of the
AD2S1200 and the AD2S1205 resolver-to-digital converters.
To evaluate the AD2S1200, order the EVAL -AD2S1200SDZ,
and to evaluate the AD2S1205, order the EVA L -AD2S1205SDZ
(see Table 7). The evaluation board can be controlled via the
SDP connector (J2). The SDP board allows the evaluation board
to be controlled through the USB port of a PC using the E VA L -
AD2S1200/05SDZ software.
On-board components include: the AD8664 precision rail-to-rail
quad op amp, the ADP1621 current mode step-up converter, the
ADM1185 4-channel voltage monitor and sequencer, the
ADP3303 high accuracy 200 mA low dropout linear regulator,
the ADP2301 step-down switching regulator, the ADP190 high-
side power switch, the ADM811 voltage supervisory device, and
the ADG3304 and ADG3308 bidirectional logic level translators.
The evaluation board features a high current driver with user
configurable gain that amplifies and biases the excitation
outputs, which allows the evaluation board to be connected
directly to a resolver. This high current driver circuit is
described in detail in Circuit Note CN-0192, available from
Analog Devices, Inc.
