Product Details

The AD604 evaluation board assembly has multiple input connections, testpoints, switch-selectable options, and on-board trims offer convenience when configuring the AD604 in various operating modes.


The evaluation board requires only a dual 5 V supply capable of 200 mA or higher to operate both channels. Prior to shipment, the evaluation board is fully tested. Users need only attach power supply leads and the appropriate test equipment to the board. See AD604 data sheet on-line for details.
