ADS7138-Q1: ADS7138-Q1

Part Number: ADS7138-Q1
Other Parts Discussed in Thread: ISO224, ADS7945

Tool/software:

Hi all,

We are planning to use ADS7138-Q1 in our design.

We are having 2 Differential signal from Output of ISO224 and 1 single ended output from Hall effect based current sensor.

Is this ADC can measure both Combination of Differential and single ended signals ? Please confirm.

Also share its schematic to proceed further process in our design.

Regards,

Babu.M

  • Hi Babu,

    The ADS7138-Q1 only accepts up to 8 single-ended inputs. It does not accept differential input signals. I'm working with my team to provide you a suitable alternative that does have differential inputs. 

    In the meantime, can you share whether you require an automotive (Q1) device, if you require an I2C or SPI interface, and if those 3 signals are the only ones you will be reading with the ADC?

    Regards,

  • Hi Joel,

    Our requirement is 3 channels only,

    Is there any part is available with differential/single ended both.

  • Hello Babu,

    The ADS1015-Q1 is a 12-bit, 4-ch ADC that takes both differential and single-ended input. Would this device solve your problem?

    Also, is this device being used in OBC or DC/DC?

  • Hi Joel, 

    I have changed my ADC to ADS7945.
