Evaluates: DG1206, DG1207DG120X Evaluation Kit General Description The DG120X evaluation kit (EV kit) provides a proven design to evaluate the DG1206/DG1207, a low-leak - age and low-charge-injection multiplexer device. The DG120XEVKIT# is fully assembled and tested, and comes populated with the DG1206EUI+, the 16-to-1 multiplexer device. Refer to the DG120X EV Kit Board Picture. 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. Benefits and Features
- SMA Connectors for Analog Inputs and Outputs
- Jumpers at A3-A0 and EN Digital Inputs for Easy Configuration
- Test Points for All Digital and Analog Signals
- Fully Assembled and Tested
- Proven PCB Layout 319-100598; Rev 0; 9/20 Ordering Information appears at end of data sheet. DG120X EV Kit Board Picture Click here to ask about the production status of specific part numbers.
- DG120XEVKIT#
- ±20V, 100mA tri-output DC power supply
- Digital multimeter Procedure The DG120X EV kit is fully assembled and tested. Follow the steps below to verify board operation: 1) Connect the three-output power supply to the DG120XEVKIT#: Set the positive voltage supply to +15V and connect to the VPOS test point. Set the negative voltage supply to -15V and connect to the VNEG test point. Connect the return of the power supply to the GND test point. 2) Verify that all jumpers are in their default positions as shown in Table 1. 3) Turn on the power supply. Ensure that both positive and negative supplies have less than 1mA (max). 4) Move shunt at J27 to position 1–2 to enable the de - vice. Verify the voltage at the EN test point is 15V. 5) Measure the on-resistance of channel 1 between COMA and NO1 at 100Ω (typ). 6) Move the shunt at J18 from position 2–3 to position 1–2. Verify the voltage at the A0 test point is 15V. 7) Measure the on-resistance of channel 2 between COMA and NO2 at 100Ω (typ). 8) Repeat steps 6 and 7 to test all 16 channels. Verify the on-resistance of each channel is 100Ω (typ). Use the relations in Table 2 to set the jumpers at A3–A0 selection inputs. Example to measure channel 8: 1) Set shunt J4 to the 2–3 (A3 = 0) position. 2) Set shunt J13 to the 1–2 (A2 = 1) position. 3) Set shunt J14 to the 1–2 (A1 = 1) position. 4) Set shunt J27 to the 1–2 (A0 = 1) position. 5) Measure the on-resistance of channel 8 between the NO8 and COMA test points.
