Analog DevicesEVAL-AD2S1205SDZDevelopment Kits and Tools

The EVAL-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 EVAL-AD2S1205SDZ 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 EVAL-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
