  • INA1650: I'm interested in configuring these amplifiers for single ended input and single ended output.

    TI Thinks Resolved
    Part Number: INA1650 I'm looking at the data sheet right now for the INA1650. Should I use the single ended design (Fig. 59 in the data sheet) for the single power supply with a dual supply? Is there an easier way to do this? I think I might still get…

  • RE: INA1650-Q1: audio line driver of AEC-Q100 solution - with 3V_rms output

    Hi Rocson, INA1650 does not include a charge pump, however, it does include a buffered supply divider which provides a mid supply reference. This would mean that the INA1650's output would be offset to mid supply, but if the customer can add DC blocking…

  • INA1650-Q1: what is the max input voltage to make Vout saturation ?

    TI Thinks Resolved
    Part Number: INA1650-Q1 Hi Team I understand INA1650-Q1 can generate max Vout = VCC - 350mV at RL = 2Kohm. could you reply to below ? thanks. I just want to know at which input voltage can make the Vout saturation. [1] at VCC = +5V and VEE…
