  • INA828: INA828 output offset, strange behaviour

    Part Number: INA828 Tool/software: Hello ! Here I have very simple gain 10 inst amp. Input is from piezo sensor (about 4nf). But with UNCONNECTED input I get about 15mV AC hum to output AND about 8mV DC offset. PCB layout is "by the book", power supply…

  • INA828: Loadcell circuit unexpectedly effected by human potential when touching body of loadcell

    TI Thinks Resolved
    Part Number: INA828 Other Parts Discussed in Thread: XTR116 , Tool/software: I have a circuit using an INA828 as the front end amplfier to a loadcell and the output 4-20mA current loop driver implemented using an XTR116. I am very happy with the performance…

  • INA828: Input bias current return path

    Resolved
    Part Number: INA828 Tool/software: Hi all, I am unsure how to handle the return path of bias current or if it is necessary. Here is how my input stage looks: As far as I can tell there needs to be a path to ground for both inputs. The non-inverting…

  • INA828: INA828 single source output limits

    Resolved
    Part Number: INA828 Other Parts Discussed in Thread: INA326 Hi, I am trying to simulate in LTspice the next circuit using INA828: Vptp = 4V Vcommon = 2.5v Vref = 2.5V Gain = 1 Vcc = 5V Vee = 0V I expect to receive output signal between 0.5-4.5V (2.5V…

  • INA828: Instrumentation Amplifiers Recomendation

    Part Number: INA828 Other Parts Discussed in Thread: INA823 ➀ Temperature specification compensation of 125°C or more and low temperature drift ② it is possible from a common-mode input range of 0V with a single supply (assuming +5V) vs an output, and…

  • RE: INA828: Generation 1 (INA128) vs Gen 2 (INA828)

    Joseph, I have received your email and will close this thread out here. Best Regards, Chris Featherstone

  • INA828: Power Supply Requirement

    Part Number: INA828 Hi Team, Can we use switching power supply to power the INA828? Or would you recommend us to use an LDO instead? The INA828 has good PSRR so I would think switching power supply should be fine. Am I right? Thanks! Roy

  • INA828: Need a replacement for this chip

    Part Number: INA828 Other Parts Discussed in Thread: INA819 We replaced INA121UA with the INA828ID Now the INA828ID is not in stock for years Is there another chip I can use with the same pad or socket Thank you
