Hello TI experts,
My customer considers AFE4404 for their new product, wearable smart wrist band.
and they want to know the answers about 2 questions below.
1. they will use photo sensor which is same as AFE4404 EVM. (NJL5513R -…
Part Number: AFE4404 Hello TI experts,
My customer considers AFE4404 for their new product.
and they want a function to measure blood pressure.
Does AFE4404 can measure blood pressure? if doesn't, please recommend another IC which can measure blood pressure…
Hello Kim,
I'm not sure if I follow what you mean, could you clarify as to what the "variable" is?
To reiterate, the calibration routine is limited in it's function, capability and compatibility. It is not intended as a go-to-market solution…

Part Number: ADS1291 Other Parts Discussed in Thread: AFE4404 ,
Hi.
I am developing with afe4404 and ads1291.
I want to measure AFE4404 and ADS1291 at the same time.
I set AFE4404 to 120Hz and ADS1291 to 500Hz.
I know that the number of data is different…
Part Number: AFE4404 Hi.
I'm measuring PPG on my wrist with AFE4404.
I look at the datasheet, 2A to 2C is LED1VAL, LED3VAL, LED2VAL.
But if you look at 2D to 2F, you get the value of ambient.
What is ambient?
I can get the value by lighting the LED…
Hi Kim,
AGC is a type of circuit relies on an analog, variable signal as a feedback input to dynamically change it's out. The AFE4404 does not have an AGC circuit. The Calibration_AFE4404.c will, through software, set configuration registers within the…
Part Number: AFE4404 Dear Sir or Madam We are having an issue regarding your AFE4404. We have a device collecting PPG samples from 3 channels - green (channel 1), red (channel 2) and infrared (channel 3). We have collected thousands of PPG signals and…
