DRV2667: Common mode voltage range of the differential input

John Levy

Part Number: DRV2667
Other Parts Discussed in Thread: DRV2700

Hi Folks,

The common mode voltage range of the differential input of the DRV2667 is not specified.

Since the absolute maximum ratings for IN+ and IN- are -0.3 to VDD+0.3 does that specify the CMVR?

The DRV2700 specifies CMRR and CMVR but it seems that the DRV2667 does not.

Given that there is no negative input voltage allowed, and you recommend ac coupling the DACs to the differential input, is there an internal offset voltage on the input pins?

Thanks

John

    Hi, John,

    Welcome to E2E and thank you for your interest in our products!

    The common mode level of the DRV2667 is determined by REG pin. It is typically, 1.75V as specified in the electrical characteristics. Please let me know if you have additional questions or comments on this.

    Best regards,
