Hello TI Support Team,
We’re using the AFE4490 breakout PCB from Protocentral as our analog front-end for PPG, heart-rate, and SpO₂ measurements. Our host is an nRF52840 Development Kit. We started with the reference…
Part Number: AFE4490 Hello.
According to the datasheet, TX_REF value should be obtained as 0.75V, but the value obtained is 0V. The designed schematic is similar to the one provided in the development guide. The crystal oscillator output is obtained…
Part Number: AFE4490 Tool/software: I am experiencing the same phenomenon as in the bellow url. The settings on each board are identical. What is the possible cause? Is it that the voltage drop is within a range that cannot be detected by a tester?
…
Part Number: AFE4490 Tool/software: AFE4490 Output Voltage On a board with a AFE4490 mounted There were some that differed only in the program. As a result, there is a possibility that the output voltage (voltage between TXP and TXN) is different by about…
Part Number: AFE4490 Tool/software: Hi TIer
My customer use AFE4490 for SPO2 product many year.
Currently , we find a pcs of abnormal chip which have abnormal LED driver SPEC.
Could you give some suggestion? If the chip is damaged?
1. TX_REF is…
