Part Number: AFE4490 It is mentioned in the datasheet, 3 to 5.25V can be used for LED_DRV_SUP and TX_CTRL_SUP.
Earlier design, we used 5V for these rails and it was proven and worked well.
Now we would like to operate these rails in 3.3V voltage level…
Part Number: AFE4490 Hi, team:
I noticed in datasheet it described “Time between both supplies stabilizing and high-going edge of RESET >100ms “, I hope to know is this a condition that T2 must meet or it is a suggestion?could you help explain the…
Part Number: AFE4490 Hi Experts,
Our customer is currently tasked with deploying the AFE4490 GUI and drivers package to a number of machines.
He has found the silent install switches required for the main setup.exe but what he is finding is the Python…
Part Number: AFE4490 使用AFE4490黑暗环境下光电二极管探测前四个寄存器得到的数据在-0.6左右波动是正常现象吗?将光电二极管换成电阻也是同样的现象,都在-0.6V。当逐渐增大LED电流时,输出结果线性上移,但是上移到+1.2之后,继续增大LED电流,输出数据为负,之后按此操作,输出结果依旧线性上移,ADC输出到达最大值之后不应该饱和吗,为什么会回到最低值?
Part Number: AFE4490 Hi,
I'm KH and I wondering AFE4490 ADC measuring voltage range.
By datasheet of AFE4490, LED1 and LED2 sample range is from +/- 1.2V.
What I wonder is why from -1.2V to 0V are needed to ADC measure.
Thank you in advance.
Part Number: AFE4490 Hi,
We are using AFE4490 with the Common anode LED configuration. For which i have below queries:
1) For LED Common anode configuration do we still require to provide supply for LED_DRV_SUP and TX_CTRL_SUP pins of AFE4490? or they…
Part Number: AFE4490 The AFE4490EVM has diodes placed at the input and output terminals:
But if we were to use the AF4490 in Common-Anode mode (instead of H-Bridge), would these diodes D1, D2, D3, and D4 still be required?
Would their purpose be for…
Part Number: AFE4490 Other Parts Discussed in Thread: 4460 , 4430 I'm looking for AFEs that are able to measure clinical-grade SpO2 and have at least 2 input channels (photodiodes).
I noticed there are a few TI AFEs (i.e. AFE4490, 4404, 4403, 4400)…

Part Number: AFE4490 Hi team,
Here's an issue from the customer may need your help:
The SPI is configured and the AFE registers are initialized, allowing register reads and writes. However, the interrupt service function cannot be entered (DRDY…
