Hello sir,

I have a query regarding TIDM-ULTRASONIC-FLOW-TDC ,

If i use a 7000mah battery to operate this design,

what will be the battery life?

Thanks & Regards,

    Hi Mit,
    There's not a simple answer to that question as the power consumption is very dependent upon sampling rate and the duty cycle you implement in an actual system implementation. Section 2.1 of the design guide states that the system consumes an average current of 10.5uA while sampling on a 1Hz rate.
    If you are interested in ultrasonic measurement of water flow, you should look at a much newer TI Design - TIDM-1019. It has replaced this reference design as our recommended solution for ultrasonic measurement.
