Part Number: ADS1252
Other Parts Discussed in Thread: ADS127L11

Hi,

Just want to confirm, the ADS1252 do not have adjustable sample rate, correct?

Do we have other alternative with a adjustable sampling rate with a this parameters below
- 24 bits resolution
- Fsample rate (adjustable) about 8, 16, 32, 44.1, 48, 96 kHz
- 1 one way of acquisition
- Power supply +5V or +/-5V or +3.3V
- Sigma Delta if possible

Regards,
Maynard

    Hi Maynard,

    The ADS1252 data rate is adjustable, but not on-the-fly. Instead, the user needs to change the clock speed (CLK) in order to change the data rate.

    We have just released a new device called the ADS127L11 that can meet these requirements: https://www.ti.com/product/ADS127L11

    This is a 24-bit delta-sigma ADC that can sample up to 1 MSPS. Additionally, the ADS127L11 offers many adjustable data rates as well as two filter types: sinc and wideband. This ADC offers bipolar supply operation, but can operate on a +5V or +3.3V supply as well.

    Please recommend this ADC to the customer. If they have specific questions about this device, please start a new thread and the appropriate support engineer will assist them there.
