Launchpad or Booster that provides a 24-bit ADC?

Greeting & Welcome,    (to a first-time poster)

The (primarily) young, female, college students - who so well support my small tech firm - note that (perhaps for 'good reason') 'No such 24-bit LPads or Boosters  are to be found here.   (or at/by competing site offerings...)

Why then - is that?    Twenty-Four bits is a 'Big Deal' and imposes a 'mighty challenge' - delivered across multiple, engineering disciplines.  (even pcb design - especially pcb design) 

So - w/those 'facts in evidence' - should it not be asked:

• why do you/your group seek such a 'high-performance - yet equally high-demanding' device?
• as 'Not being Readily Available' - are you/your group - prepared to 'roll your own?'

You may note that many (perhaps most) of the 'pro firms' who deploy such devices (20/22/24 bits) do so to enhance, 'Dynamic Signal Range' - not just added signal resolution.

It is believed that 16 bits - perhaps even 18 bits - are far more likely to be (somewhere) available - and (they) may prove a superior choice.     In addition - your use of a 'ready made/tested' Eval Board (not only a Booster) is much preferred over a 'user attempted - pcb design & layout.'     Bread-boards - almost surely - have  'No chance of succeeding' at this level of  ADC resolution.

Hi 

For MSP430, we have some 24-bit sigma delta devices. You can refer to this http://www.ti.com/microcontrollers/msp430-ultra-low-power-mcus/products.html#~p121=24-bit%20Sigma%20Delta

That is better to provide more information about your project and we will give you a better choice.

Best regards

Gary

Hi Gary!  My project is a wheatstone with a desired step resolution of ~25-35uV and a total range of ~8mV.

To resolve that with minimal error, I believe I'd need >18-bits, ENOB.   It seems like the TI mcu ecosystem has on-board ADC offerings in (mostly) 16-bits then jumps to 24-bits.

I am not at all familiar with TI products though.

It would be ideal to start with a launchpad, for ease of entry into the IDE.  But alternately, I will try a non-launchpad mcu.

Or a separate ADC.  The ADS1220 keeps coming across my radar.  But I am not sure if this is a great product for this application.
