Part Number: AFE4403 Hi ,
We want to read registers 0x2A to 0x2F in a single SPI transmission. The datasheet said it support "Multiple data reads and writes"(ch8.5.2.3). So we attempted an SPI transfer (address set to 0x2A, read length 18 bytes), but…
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 ?
Regards…
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.
Regards,
Anurag
