ADC122S655: Is there a similar part that runs off 3V or 3.3V supply?

Hi

We do not have part with simultaneous sampling operating at 3V or 3.3V. Can you please let me now below details

1. Number of channels required

2. Input type: Fully differential / Pseudo Differential / Single Ended

3. Maximum throughput required

Based on your inputs I can see if combination of some of the existing devices can be used to meet your requirement

Thanks & Regards

Hi

If you are specifically looking for 12 bit resolution then I would recommend you to take look at ADS704x family. You can use two of ADS704x. You can tie together chip select pin from each ADC (CS) and use same clock for conversion. So you will need 4 digital lines

1. Chip select (same for both ADC)

2. Clock (same for both ADC)

3. SDO1 and SDO2 of individual ADC

Let me know if this approach looks ok

Thanks & Regards

Need 2 fully differential channels that will be sampled simultaneously. I'm flexible on resolution and sample rate. The signals are effectively DC - 10 kHz bandwidth. SPI or other serial interface. WOuld like to accomplish this in a single device.
Thank you.

Hi JB63

Can you please take a look at ADS7863A. It is dual 2MSPS 2+@ simultaneous sampling SAR ADC. It has total 4 channels as against your requirement od 2 channles. But this is the closest I can find that match your requirements

Thanks & Regards
