LTC5594 - DC2465A and DC590B show the Cannot load module for device with right connection
Please verify the supply voltage and current are correct. Adjust Vsupply until Vsense is 5V. The supply current should be about 470mA. Vcm should be 0.9V or floating. (Be aware that the 4 IF outputs have 0.9V common-mode voltage on them.) The jumper for Vlogic should be set to "INT" position. Make sure the DC590B's VCCIO jumper is set to 3.3V.
