  • LMC660

    Other Parts Discussed in Thread: LMC660 Dear TI, In one of our products (VFD), we use the LMC660 to monitor/measure the main voltages (L1,L2 and L3). When the AO Amp is turned-on (t=0s), a positive glitch/whisker appears on the output pin of the component…

  • LMC660: Voltage on + input when floating

    Part Number: LMC660 Other Parts Discussed in Thread: LMP7701 , LMP7721 I am using one LMC660 to measure 4 different voltage levels. I have it wired as 4 different non-inverting buffers that then go into an ADC. I am seeing that when the +Input is left floating…

  • RE: TLV9102: INPUT Impedance of TLV9102

    Resolved
    Hi Hari, you can still have the (many) LMC660 sitting outside Another option is to mount the LMC660 close to the ASIC and to cool the LMC660 by an air stream. Install the LMC660 in a small thermally isolating enclosure and connect two pipes to the enclosure…

  • contactless electrode with lmc660

    Other Parts Discussed in Thread: LMC660 , LMC6482 , LMC6442 , LMP7702 , LMC6484 , LMC6001 , INA326 , TINA-TI Hi, I have some lmc660 ic and I want to design a non contact active electrode my question is it suitable ic for replacing with lmc6442 or lmc6482 because…

  • RE: PGA204: How to configure IA for best results with high source impedance.

    HI Jeremy, Please see below the OPA3S328 configured on a programmable gain amplifier configuration. The OPA3S328 input impedance is high since it is intended for transimpedance amplifier applications (but not as high as the ultra low leakage LMP7721 or…
