  • OPA810: How to improve amplifer circuit noise

    Part Number: OPA810 Other Parts Discussed in Thread: THS4551 , , TINA-TI Hello, Please see below issue. We located the root cause is from amplifier circuit. I would like to ask how to calculate the noise based on current power design. How to improve…

  • OPA810: Supply current per amplifier

    TI Thinks Resolved
    Part Number: OPA810 Hi, I am looking for supply current per amplifier of the op-amp part OPA810IDCKR. In the datasheet Quiescent current per amplifier is given i.e. 4.7mA maximum (for +/-12V supply), supply current is not given in datasheet. Please…

  • OPA810: Input Offset Voltage vs Input Common-Mode Voltage (Vs+ = 5V, Vs- = 0V)

    Resolved
    Part Number: OPA810 Hi team, The customer would like to check the Vos - Vcm chart under Vs+ = 5V, Vs- = 0V. They've checked Figure 7-41 in the datasheet but it seems that chart is for Vs = +- 2.5V. Could you check it and share us the chart for…

  • OPA810: bias current

    TI Thinks Resolved
    Part Number: OPA810 Hi Team, Customer wants to double check for OPA810 input bias current polarity, datasheet doesn't provide negative sign, so assume it's always one direction current? And meaning in or out? From below graph, it seems like bias…

  • RE: OPA810: PSpice model issues

    Resolved
    Update: It turns out I can't tie both inputs to a reference voltage either; apparently the only way I can get the simulation to converge is by tying both inputs to the "0" (circuit common) net. Also, my link to the model didn't come through last time…

  • RE: OPA810: External circuit

    Hi, yes the corner frequency of 99 Hz is optimal. I need the gain and i have to use a non-invering topology. So i have to integrate the signal in that way, am i right? and with the Servo loop as a noninverting high pass filter the simulation doesnt…
