Part Number: ADS1294 Other Parts Discussed in Thread: ADS1298 The ADS129x datasheet says all unused inputs should be tied high. Since the one datasheet encompasses different devices with different numbers of inputs, the statement is a bit nebulous.
Are…
Part Number: ADS1294 I have a question about ADS1294's SPI MODE. DATASHEET 7.7 Switching Characteristics says SPI setting is CPOL=0 and CPHA=1. 1. I would like to ask if I can change the SPI MODE by changing the register. If you can change it, I'll…
Hi Kailyn,
Since it's been over a week without a response, I must assume the problem has been solved . Please reach out to me directly via email for updates on this topic.
Kind regards, Nick Z
Part Number: ADS1294 Hello,
Can someone check my schematic for any issue. I am using 3 out of 4 channel of ADS1294. I am not seeing any voltage across DVDD which should be 1.8V. While other voltages AVDD(+2.5V) & AVSS(-2.5V) are supplied to the chip.…
Part Number: ADS1294 Other Parts Discussed in Thread: ADS1298ECGFE-PDK Hello,
I am using ADS1294 and trying to measure signal from Channel 2. I am not sure if I am configuring the registers of ADS 1294 correctly. I am able to read and write data to the…
Part Number: ADS1294 Other Parts Discussed in Thread: ADS1298 I have a question about SPI SCLK while using ADS1294. SCLK PERIOD 66.6 ns (MAX 15 MHz) on DATASHEET, but if it actually works, it is fine from 1 to 5 MHz, but data corruption from 6 MHz will…
Part Number: ADS1294 Hello, I have a question about the mixed use of pace detection and AC lead off detection.
Because I need to use dry electrodes in my scene, I need to choose an AC lead off detection scheme, and then I need to carry out pace detection.…
Part Number: ADS1294 Hi team,
A customer wanted to double check the power dissipation spec in the datasheet of ADS1294. Would you please reply the followings?
1. From bellow table, is the power dissipation the sum of IAVDD*AVDD + IDVDD*DVDD? However, the…
Part Number: ADS1294 I've had the entire chip (DVDD, 1.8V) as well as its power supplies (+/-1.5V) on a separate supply chain that was tied to PWDN/RESET. Thus, a LOW on that line would shutdown everything. I'm considering just putting the bipolar…
Part Number: ADS1294
I realize that THD and INL are different for channel 1, but I'm not sure if that can explain my observation that channel 1, when input shorted OR measuring real signals, is different by a factor of 1,000. I've read back the CHnSet…
