Need help to find out 3.3V, 12-bit, bipolar input (+/-10V range) ADC

Hello All,

I am looking for an ADC with the below features:

Bipolar input (+/-10V range)

12-bit resolution

100 KHz sampling rate

10 microsec throughput speed

and most importantly it should operate on a single 3.3V

  In the existing design, the ADC used is ADS7808 which operates on single 5V supply. But in my new design, I want to use the 3.3V technology only. I also have +/-15V supplies on the board.

I am not able to find the ADC's which can operate on 3.3V and support bipolar input range of +/-10V with any manufacturers. Is it possible to design in such away?

 

Please help me in finding the suitable ADC for my new design.

 

Many Thanks in advance,

Kiran

    Hi Kiran,

    The AD5724R would be a possible option in this case, as well as the AD5726.

    They are both serial interface, quad DACs with compatible functionality to the DAC7615.

    The AD5724R, as opposed to the AD5726, offers the SDO pin with which the DAC can work in daisy-chain or readback mode.

    For the pin compatibility, the AD5724R comes in 24-Lead TSSOP packages.

    The AD5726, with 16-Lead SSOP and 20-Lead SSOP packages, would be pin compatible with DAC7615.

    The AD5724R and AD5726 are new products which will be available for a minimum lifetime of 10 years.

    Regards,
