  • INAEVM-SO8: differential measurement by means of instrumenation amplifiers

    Part Number: INAEVM-SO8 Hi, in order to implement an analog-to-digital conversion (input range of at least -6V to +6V) I wanted to check and survey some instrumentation amplifiers which are intended for driving the ADC. Therefor, I used the INAEVM-SO…

  • RE: INA116: PCB layout

    HI Aida, The INA116 is a legacy device and it is not recommended for new designs. The INA121 FET input, low power, instrumentation amplifier is a possible replacement. The INA121 has lower offset and higher CMRR with half the power consumption: https…

  • INAEVM Mechanical Drawing

    TI Thinks Resolved
    Other Parts Discussed in Thread: INAEVM Precision Team, I have a customer looking for the mechanical drawings for the INAEVMs. The UG does not include dimensions. Where can these be found or can you post? INAEVM - http://www.ti.com/tool/INAEVM?keyMatch…

  • INA849: Overshoot control

    Part Number: INA849 Other Parts Discussed in Thread: ADC3643EVM , , INAEVM-ALT-SO8 , ADC3643 Hello TI Team, I am currently working on the INA849 that I would like to use to feed the input of an ADC3643EVM board. It is connected to a square wave generator…

  • INA333-Q1: Could you tell me how which part and how we use for its EVM?

    Resolved
    Part Number: INA333-Q1 Hi team, Could you tell me which EVM and how we use it for INA333-Q1 evaluation? Is "INAEVM-MSOP8" suitable for INA333-Q1 VSSOP? Is it EVM without INA device and we need additional INA333-Q1 IC itself to evaluate INA333…

  • INA333: gain is not as expected

    TI Thinks Resolved
    Part Number: INA333 Hi, I'm using INAEVM-MSOP8 to test INA333 with below configuration. V+=2.5V, V- = -2.5V. REF=0V, RG=1K, which sets GAIN=100. Although IN- is not connected to GND, but I measured the common mode voltage is only 0.6mV. IN+ -IN-, …

  • INA333: output has large ripple

    TI Thinks Resolved
    Part Number: INA333 Hi, I'm using INAEVM-MSOP8 to test INA333 with below configuration. V+=3.3V, V- = 0V. REF=0.3V(not to GND shown in the picture), IN- to GND is 1.65V(add a 1.65V reference from IN- to GND), RG=536ohm, which sets GAIN=187. when…

  • RE: TLV333 Reference circuitry to with IR THERMOPILE

    Hi Manoj, I did not find specific TC EVM, but we have universal instrumentation Op Amp EVB, which it will make your design slightly easier. https://www.ti.com/tool/INAEVM-SO8#technicaldocuments https://www.ti.com/lit/ug/sbou122b/sbou122b.pdf?ts=1594657231310&ref_url…

  • RE: TINA/Spice/INA333: CMRR plot

    Hi Ian, Thank you for suggestion on VCVS1. It makes sense. I was wondering if its possible to do a bench measurement of the CMRR with a function generator and oscilloscope. Where can I find guidelines to do so ? I also have the INAEVM-MSOP8 evaluation…
