eval - ad7403fmcz user guide ug- 683 rev. 0 | page 7 of 20 evaluation board har dware ad7403 description this user guide describes the evaluation board for the ad7403 isolated adc . the ad7403 is a second - order, - modulator that converts an analog input signal into a high speed, 1 - bit data stream with on - chip digit al isolation based on analog devices , inc., i coupler technology. the ad7403 operates from a 5 v (v dd1 ) power supply and accepts a differential input signal of 250 mv (320 mv full scale). the differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required. the analog input is continuousl y sampled by a high performance analog modulator and converted to a ones density, digital output stream with a data rate of up to 20 mhz. the original information can be reconstructed with an appropriate digital filter. the serial i/o can use a 5 v or a 3. 3 v supply (v dd2 ). the serial interface is digitally isolated. high speed cmos, combined with monolithic transformer technology, allows the on - chip isolation to provide outstanding performance characteristics that are superior to the performance of alterna tives , such as optocoupler devices. the ad7403 device is offered in a 16 - lead , wide - body soic package and has an operating temperature range of ?40c to +125c. complete specificat ions for the ad7403 device are provided in the ad7403 data sheet and should be consulted in conjunction with this user guide when using the evaluation boa rd. full details on the e va l - sdp - ch1z are available on the sdp - h1 product page . power supplies care should be taken before applying power and signals to the evaluation board to ensure that all link positions are set according to the required operating mode. see table 2 for the complete list of link options. this evaluation board is designed to be supplied via the e va l - sdp - ch1z . the e va l - sdp - ch1z generates 12 v and 3.3 v supply rails. the 12 v supply is connected to the on - board 5 v linear regulator that supplies the adum6000 wi th power. the adum6000 generates an isolated 5 v supply to power the v dd1 rail of the ad7403 . the 3.3 v supply rail from the e va l - sdp - ch1z is used to supply the v dd2 rail of the ad7403 . if the user wishes to supply v dd1 externally, an external power supply in the range of 2 4 v 5% can be connected to the high_v connector, j7. alternatively , an external supp ly in the range of 5 v 10% can be connected to the j5 connector. the v dd2 supply can also be supplied via an external power supply in the range of 3 v to 5.5 v via the j6 connector. there are two main ground planes : gnd 1 and gnd 2 . these planes are isolated with a creep a ge and clearance of 8 mm. caution when th e e va l - ad7403fmcz is connected to the e va l - sdp - ch1z , care must be taken to ensure that if an external voltage is supplied to the j6 input connector , the voltage does not exceed 3.3 v. exceeding this voltage may cause permanent damage to the e va l - sdp - ch1z board. input signals the analog input range to the ad7403 is 250 mv (320 mv full s cale), which should not be exceeded. an input signal in the range of 500 mv p - p should be connected to the evaluation board via the analog input connector, j1. the e va l - ad7403fmcz has analog and digital ground planes that are physically isolated from one other. as such, power to the analog supply rail is by default, supplied through the on - board adum6000 isolated i coupler 5 kv, dc - to - dc converter. v dd1 can optionally be supplied from the j5 external connector or from the j7 high voltage external connector. a 24 v supply connected to j7 is stepped down to 5 v by means of the on - board adp2441 step - down dc - to - dc regulator. see table 2 for more information about supplying v dd1 externally. table 1 . external power supplies (optional) power supply connector voltage range pu rpose v dd1 j5 5 v 10% analog supply rail v dd2 j6 3 v to 5.5 v digital supply rail without eval - sdp - ch1z connected 3.3 v 5% digital supply rail with eval - sdp - ch1z connected high_v j7 24 v 5% analog supply rail (high voltage alternative to j5)
