ADS131E04: Fast power up type ADC

Pravin Vadhiyar
Prodigy 10 points
Part Number: ADS131E04
Other Parts Discussed in Thread: ADS131E08S, ADS131A04

We have used ADS131E04 ADC in our one product. I would like to reuse same for another product we are starting design. Only one parameter is not suitable as Power up timing of ADS131E04 is @150ms.I have calculated base on datasheet data.my design requirement is fast or <=20ms.can you proposed suitable alternate part number?

    Hi Pravin,

    Apologies for the delay in response. 

    The closest option will be the ADS131E08S, which as shown in "5 Device Comparison" of the datasheet, has a power-up time of 3ms. 

    Another option is the ADS131A04 which settles to 0.1% within 1.2ms, 0.001% after 250ms. This device also features a faster maximum sampling rate.
