  • VCA2615: VCA2615

    TI Thinks Resolved
    Part Number: VCA2615 Hello all, I use VCA2615 in ultrasonic application. On the page 18 of Data Sheet Table 5. shows codes for Feedback Resistor Settings. I have come across that setting any code other than '1111' (Open) causes a significant increase in…

  • RE: VCA2615: Amplifiers forum

    Hi Victor, Apologies that I missed this message. I had replied quite a while back and seems like somehow my reply didn't went through earlier. I calculated the Rin for 18dB (similar to yours at 22dB). That's all. For an amplifier say non inverting…

    Hi Bellala, Thank you for this! I have sent an email for direct support.

  • VCA2615: The difference of control gain amplitude between VGA chips exceeds the specification limit

    TI Thinks Resolved
    Part Number: VCA2615 Hello! We have some questions when using vca2615rgzt. I hope you can give me some help and answers. Problem: we use vca2615 as part of automatic gain control. Under the condition of almost the same input and output, the maximum difference…

  • RE: ADS5263: Optimal input impedance termination

    Hi, How are you! Thank you for using TI VCA2615 and ADS5263 devices. Since you are using VCA2615 to drive ADS5263 (as close as possible), then only VCA2615 needs to take care of the input signal termination. Also because ADC input pins are also driven…
