    TI Thinks Resolved
    Part Number: OPA856 Other Parts Discussed in Thread: LM828 , LM27761 , TPS60400 Hi , I'm using OPA856 Op-amp in my simulation as error amplifier. In this op-amp i need to give Negative Voltage supply for VS– Pin, Here i've choosen LM828 (Switched…

  • ADS124S08: Can I use a voltage converter from REFOUT (like LM828 or LM2664) to supply REFN0 and AVSS?

    Part Number: ADS124S08 Other Parts Discussed in Thread: LM2664 , , LM828 Hi all, I want to use the ADS124S08 with a +2.5vdc (AVDD) and -2.5vdc (AVSS) analog voltage supply, 3vdc for the digital supplies (DVDD and IOVDD). I'm wondering if I can use the REFOUT…

  • LM828: About charge-pump capacitor.

    TI Thinks Resolved
    Part Number: LM828 Other Parts Discussed in Thread: LM2776 , TPS60400 Hello E2E team. I have a question about charge-pump capacitor for LM828. Would it be possible for charge-pump capacitor to use of ceramic capacitor instead of electric capacitor? Thanks…

  • LM828 inverting charge pump converts only about 85% of the positive input voltage

    Other Parts Discussed in Thread: TL974 , LM828 , LM324 , CC3200 , LMV324 , LM2663 , LM2664 I'm trying to create a +/- 3.3V rail for a TL974 opamp. I'm using the LM828 switched capacitor voltage converter for creating the negative rail. I've used the schematic…

  • RE: INA333: Why there is a huge spike on the peak on the ina333 out put

    Resolved
    I would recommend scoping your power supply line. That ripple seems odd and roughly calculates to 17kHz, while the LM828 is specified for around 12 kHz. Nonetheless your charge pump power supply should be scoped to be sure it is not the cause of the problem…
