  • INA828: Slow amplitude oscillation at the INA828 Output

    Part Number: INA828 Other Parts Discussed in Thread: ADS1278 , , TINA-TI Hello, i am trying to design an circuit which needs to sample a 50Hz signal, at very low voltages 10[mV] - 5V peak. This is the tested design: In this configuration i get…

  • 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…

  • INA828: IN828 vs. INA818

    Part Number: INA828 Other Parts Discussed in Thread: INA818 , INA118 , INA819 , INA826 Tool/software: We have a circuit that previously used a competing device the LT1167A. To increase Overvoltage and ESD protection we switched to the INA818 since it…
