Hi Winston,
Thank you for your post!
The SAR ADC solution shown in TIPD197 is just an example of how this application could be done. You can a different ADC if you'd like, as long as the sampling rate and resolution meet your performance criteria…
Part Number: TIPD197 When testing pace sensing devices, how does TI model the heart as a circuit to account for its impedance and frequency response? I would like to test a device that is measuring intracardiac signals, but I need to first design a circuit…
Part Number: ADS1293 Other Parts Discussed in Thread: TIPD197 I am using ADS1293 for my heartrate application. Need to create external circuitry for pacemaker signal remove and detection?
Can I use the TIPD197 as a reference circuit for pacemaker detection…
Part Number: ADS1298 Other Parts Discussed in Thread: TIPD197 Hi colleague,
The customer is using our ADS1298, now they want to add pacemaker detection.
They concern that:
1. Just use ADS1298, the software calculates.
2. Use ADS1298 pace out …
Hello Takumi-san,
We have these two reference designs regarding pace detect: TIPD111 and TIPD197 . Note that for the ADS1293, there are high sample rate dedicated pace channels, so an external op-amp and SAR ADC is not required for software pace detection…
Hey Sarin,
I cannot provide the exact internal connections of the VCAP2 pin since the design for the ADS1298 is proprietary. What I can say is that you are not able to change the values of any of the resistors internal to the device.
In TIPD197…
Hi Chase,
Thanks for the support.
The ADS1294 offers the flexibility for pace detection by using either software (internal ADC) or external hardware. There is some design tradeoff between the software and hardware approach. The internal ADC (max 32…
Part Number: ADS1198 Other Parts Discussed in Thread: ADS1298 Our customer plans to open a new product of ECG monitoring, which needs an 8-channel low-power ECG scheme. We plan to use ads1298 to design and be compatible with ads1198 at the same time.…
