way is that the current can be measured by on board precise resistor used for I-to-V conversion. The small voltage signal amplified by operation amplifier and given to ADC. Then it can be calculated by LPC4322 and shown in MCUXpresso IDE. Another way is that the current is measured by external Ammeter through Jumper JP14. 3.2.1 Current Test using LPC4322 The QN908x DK board has an on-board current measurement circuit consisting of a MAX9634T (U18) current monitor chip and a 12-bit ADC (ADC122S021, U19) with a 12-

bit sample at 50k to 200ksps. The on-board MAX9634T current monitor measures the voltage across the QN908x VCC V-sense resistors; either 8.24 or 4.12 if JP13 is installed. The MAX9634 multiplies the sense voltage by 25 times to provide a voltage range suitable for the ADC to measure. A 2-input analog mux is used to choose which channel to be measured, the QN9080 or the devices from expansion board on the DK extension connectors. The current measurement circuit is controlled by the Link2 processor and is not user programmable. Power measurement utilities with this feature are available only after MCUXpresso IDE installation. Due to input offset voltage variations in the MAX9634, the current measurement circuit is not recommended for measuring current below 150uA. The QN908x current can be measured by the voltage across a sense resistor in series with the supply. The voltage across a series 4.12 resistor with the target QN908x VCC can be manually measured at JP12 on the PCB. Use Ohms law to calculate the current

(QN908x current = measured voltage / 4.12). As an example, if the measured voltage is 10mV, then 10e-3 / 4.12 = 2.44mA. Note that the current consumed by the MAX9634 used in the on-board current measurement will be included in the voltage measured across this resistor. The detailed schematic shown in Figure 12.

The other way is using the DC Power Analyzer as the power supply to DUT. In this case, the QN9080 Module is power by DC Power Analyzer. The QN_VCC power pin is on Jumper JP14, where a triangle symbol indicates the pin. Also, there is a GND pin nearby Jumper JP2, which can be used as power ground.
