5.4 Test Procedure

Figure 5 shows a typical setup for the R

test of the EVM. VBIAS voltage must be present for the device

to function, keep this voltage level constant between 2.5V-5.25V. Adding a shunt across JP1 will connect

the VBIAS pin to VIN1. When testing with VIN1 below 2.5V JP1 shunt must be removed and VBIAS tied to

another voltage source. It is recommended to keep VBIAS voltage level at 5V. Datasheet specifications

were taken with VBIAS = 5V.
