Evaluates: DG1206, DG1207 DG120X Evaluation Kit General Description Benefits and Features The DG120X evaluation kit (EV kit) provides a proven SMA Connectors for Analog Inputs and Outputs design to evaluate the DG1206/DG1207, a low-leak- Jumpers at A3-A0 and EN Digital Inputs for Easy age and low-charge-injection multiplexer device. The Configuration DG120XEVKIT is fully assembled and tested, and Test Points for All Digital and Analog Signals comes populated with the DG1206EUI+, the 16-to-1 Fully Assembled and Tested multiplexer device. Refer to the DG120X EV Kit Board Proven PCB Layout Picture. Ordering Information appears at end of data sheet. The DG120XEVKIT can also be used to evaluate DG1207, the 8-to-1 device from the same multiplexer family. See the Configure the DG120X EV Kit section for more information.

Verify the voltage at the EN test point is 15V. Recommended Equipment 5) Measure the on-resistance of channel 1 between DG120XEVKIT COMA and NO1 at 100 (typ). 20V, 100mA tri-output DC power supply 6) Move the shunt at J18 from position 23 to position Digital multimeter 12. Verify the voltage at the A0 test point is 15V. 7) Measure the on-resistance of channel 2 between Procedure COMA and NO2 at 100 (typ). The DG120X EV kit is fully assembled and tested. Follow 8) Repeat steps 6 and 7 to test all 16 channels. Verify the steps below to verify board operation: the on-resistance of each channel is 100 (typ). Use 1) Connect the three-output power supply to the the relations in Table 2 to set the jumpers at A3A0 DG120XEVKIT : selection inputs. Set the positive voltage supply to +15V and connect Example to measure channel 8: to the VPOS test point. 1) Set shunt J4 to the 23 (A3 = 0) position. Set the negative voltage supply to -15V and connect to the VNEG test point. 2) Set shunt J13 to the 12 (A2 = 1) position. Connect the return of the power supply to the GND 3) Set shunt J14 to the 12 (A1 = 1) position. test point. 4) Set shunt J27 to the 12 (A0 = 1) position. 2) Verify that all jumpers are in their default positions as 5) Measure the on-resistance of channel 8 between the shown in Table 1. NO8 and COMA test points. 3) Turn on the power supply. Ensure that both positive and negative supplies have less than 1mA (max). Table 1.
