Texas Instruments THS4503EVM manual 2.1Required Equipment, 2.2Power Supply Connection Refer to −1

Required Equipment

2.1Required Equipment

-One dual-output dc power supply (±5 V, 1 A output minimum)

-Two dc current meters with resolution to 1 mA and capable of the maximum current the dc power supply can supply.

-50-Ω source impedance function generator (1 MHz, 10 VPP sine wave)

-Oscilloscope (50-MHz bandwidth minimum, 50-Ω input impedance)

-3 BNC-to-SMA cables

-BNC-to-BNC cable

-5 Banana-to-Banana wires; 4 red, 1 black

2.2Power Supply Connection (Refer to Figure 2−1)

1)Set the dual dc power supply to ±5 V. If available, set the current limit on the dc power supply to 100 mA.

2)Make sure the dual dc power supply is turned off before proceeding to the next step.

3)Connect the positive (+) terminal of the power supply to the positive (+) terminal of the current meter number 1.

4)Connect the negative (–) terminal of the current meter number 1 to +VS (J8).

5)Connect the common ground terminal of the power supply to GND (J7).

6)Connect the negative (–) terminal of the power supply to the negative (–) terminal of the second current meter.

7)Connect the positive (+) terminal of the current meter number 2 to –VS (J5).
