Re: Patient Monitoring
Just to be clear - you'll still want a good intrmentation ampto be able to achieve the needed very high CMRR.

Re: BLE + Gateway = Analog for Everybody
Oh - and medical apps - sorry - forgot that one - both in the hospital/clinic and in the home. That's what I was hinting at w/ "western PA."

Transducer AFEs
Tres cool application development tool!

This reminds me of a challenge for designers of transducer based systems: Performance confirmation for transducers and their signal conditioners requires a reference in the transducer's input domain. In this case, for example, one would need reference gas samples to confirm a gas detector's baseline and span accuracy.

I know there are a number of ways of confirming gas composition, but there are other transducer types with less obvious references. An example that I've found vexing is that of acoustic measurements: Acoustic transducers  speakers  are characterized with measurement microphones. Does anyone know what manufacturers use to calibrate or confirm the response of the measurement microphones? Where do you buy reference SPLs over a spectrum?

Re: Patient Monitoring
Hmm... multiple ADCs? Very nice. I've been involved in some product designs in the past that could have greatly benefitted from such an IC.

Patient Monitoring
AFEs from TI are very valuable. I have been using the ADS1298R for ECG application. It provides easy integration with MCU and has everything a good ECG preamp has. What interested me most was, the device was able to do all this with separate 24 bit ADCs for each channel. Simultaneous sampling of signals - to the letter.

Re: BLE + Gateway = Analog for Everybody
I agree - cool stuff. I hadn't been watching TI's low power devices much, but now that I see what they're doing, I'll pay more attention. Their devices should be useful for companies doing smart home, home automation, and remote [utility] meter reading apps.

BLE + Gateway = Analog for Everybody
Hi Brad--this is totally cool.  The TI guys have been leading the ultra-low power wireless area, and adding integration to integrate to senosrs will just make it that much easier for users.  This enables connecting all sensors in your building or factory to Bluetooth (Low Energy, of course) then using gateways to aggregate all those BT devices onto a LAN or WLAN (WiFi).  Bingo, you have your analog sensors on your network.
