Part Number: AFE4403 Tool/software: Hi ,
I am working with AFE4403 part. I wanted to have the latest driver compatible with Linux BSP version 6.1.8
The one I found seems to be older one.
Kindly share the latest driver if available.
Part Number: AFE4403 Tool/software: Hi,
I am trying to design SPO2 circuit using AFE4403. I have a question regarding pin A4 (TXN) i.e. LED driver out.
Is it possible to have 5V (externally) on pin A4 when AFE4403 is in power down mode ?

Part Number: AFE4403 Tool/software: Hi, I want to use AFE4403 to drive UV LED in common anode mode, the LED required Voltage is 5-7V, since the max voltage is 5.25-0.5=4.75v ? Is it possible the drive this UV LED ?
If the 4403 cannot directly provide…
Part Number: AFE4403 Tool/software: I have introduced a short NPSCGND: INP to GND diagnostic flag and enabled diagnostic mode by writing 0x04 to register 0x00. I see a pulse at DIAG_END pin and later when 0x30 register is read, it always returns 0x00…
Part Number: AFE4403 Tool/software: Do we need to consider analog and digital grounding in the design in such a way that RX_ANA_GND will be separated from rest of the digital ground ?
Part Number: AFE4403 Hi,
I have set LED current to 50 mA and I am trying to verify it by having a 100 ohm resistor accross TXP and TXN.
I am getting voltage waveform with 4V max value. As per my understading the voltage sould be around 5V.
I am…
Part Number: AFE4403 We are in the process of developing a portable SpO2 machine using the SFH7050A sensor (comprising an LED and PD) and the AFE4403. We have two ideas for the design configuration:
1. Placing the LED and PD on one PCB while locating…
Part Number: AFE4403 Hi,
Request you to confirm range of values for Tx_REF for 5.25V supply.
It is not clear from datasheet if for 5.25 supply Tx_Ref can only be 0.75V or 1V or it can be 0.5V or 0.25V as well.

Anurag
Part Number: AFE4403 I have a question about AFE4403. Depending on the circuit configuration and software SPO2 (Blood Oxygen Saturation) and HRM (Heart Rate per Minute) Can you measure at the same time?
If possible, where in the datasheet the circuit…
