ADS131A04: bandwidth of ADS131A04

Part Number: ADS131A04

Hi expert,

Do you know the the bandwidth of ADS131A04? Cause I can't find it on datasheet.

By the way, do you know what's the main differences between ADS131A0X, ADS131M0X, ADS131E0X？

    Hello Jiandong,

    Thank you for your post.

    The bandwidth of the ADS131A04 is determined by the digital filter response, which varies with data rate. The analog signal bandwidth that can pass through the input to the ADC sampling circuitry is much, much higher frequency, so we typically do not specify this.

    A comparison of the ADS131xxx family is found in the attached PPT slide below. The ADS131Exx has a much higher input impedance, while the ADS131A0x and ADS131M0x offer improved AC specifications. The ADS131A0x and ADS131M0x also offer free-running synchronous interface options in addition to the asynchronous SPI.
