Part Number: TDC1000

HI,

     i am working on water flow meter so am using 1Mhz transducer Audio-well Transducer,This Transducer needs 3V to 5V peak to peak voltage but am getting only 750mV at the TX pin of TDC-1000. what would be the problem or how can i boost voltage level in TDC1000 TXpin.

    Hello Rashmi,

    My apologies for the delayed response. Most of our engineers are on holiday currently. Please reference the TDC1000-GASEVM, which supports higher voltages: www.ti.com/.../tdc1000-gasevm

    You'll be able to find the schematics and configuration from that page.

    Best regards,
    Blair
