Evaluates: DG1208, DG1209 DG1208, DG1209 Evaluation Kits General Description Features The DG1208/DG1209 evaluation kits (EV kits) pro- SMA Connectors for Analog Inputs and Outputs vide a proven design to evaluate the DG1208/DG1209, Jumpers at Enable and Address Selection Inputs for low-leakage and low-charge-injection multiplexer devic- Easy Configuration es. The DG1208EVKIT and DG1209EVKIT are fully Test Points for All Digital and Analog Signals assembled and tested, and come populated with the Fully Assembled and Tested DG1208EUE+ and DG1209EUE+ multiplexers, respec- tively. The DG1208 is a single 8-to-1 multiplexing device Proven PCB Layout the DG1209 is a dual 4-to-1 device. Both multiplexer devices are available in 4mm x 4mm 16-lead TQFN or Ordering Information appears at end of data sheet. 16-lead TSSOP packages.

Recommended Equipment 3) Turn on the power supply. Ensure that both positive DG1208EVKIT and negative supplies have less than 1mA (max). 4) Move the shunt at J15 to position 12 to enable the 20V, 100mA tri-output DC power supply device. Verify the voltage at the EN test point is 15V. Digital multimeter 5) Measure the on-resistance of channel 1 between COM and NO1 at 100 (typ). Procedure 6) Move the shunt at J14 from position 23 to position The DG1208EVKIT is fully assembled and tested. 12. Verify the voltage at the A0 test point is 15V. Follow the steps below to verify board operation: 7) Measure the on-resistance of channel 2 between 1) Connect the tri-output power supply to the COM and NO2 at 100 (typ). DG1208EVKIT : 8) Repeat steps 6 and 7 to test all 8 channels. Verify Set the positive voltage supply to +15V and con- the on-resistance of each channel is 100 (typ). Use nect to the VPOS test point. the relations in Table 2 to set the jumpers at A2A0 selection inputs. Set the negative voltage supply to -15V and con- nect to the VNEG test point. Connect the return of the power supply to GND test point. Table 1. DG1208 EV Kit Shunt Positions JUMPER SHUNT POSITION DESCRIPTION NO CHANNELS Open Disconnect NO1 to SMA connector J6.
