  • PCM1865: PCM1865 and OPA1637 conection

    Part Number: PCM1865 Hi, I have connected PCM1865's Vref to my OPA1865's VCOM, im wondering if i should divide it by two or not. My OPA is conected to +18v / -18v. But Ive read VCOM should be connected to AVDD/2 so im not sure. Should i divide…

  • OPA2197: Alternative to OPA2197

    TI Thinks Resolved
    Part Number: OPA2197 Other Parts Discussed in Thread: OPA2350 , OPA2156 Hi, In one circuit, it was found that the slew rate of the OPA was slow and affected the measurement accuracy. So when OPA2197 with a high slew rate was used, an improvement in accuracy…

  • RE: ADC3422: adc3422 output data issue

    Resolved
    I removed the resistor between OPA and ADC. I observed CHA is much better than CHC and CHD. So, I can not conclude it's OPA issue.

  • RE: Cdd_Ipc Schema File is having DemEventParameterRef but there is no DemEvent mentioned as part of MCAL_AM263x_08.06.02.01 package

    Hi Pradeep, Yes there is a option in the XDM, however if I understand this correctly this is an optional field isn' it? I see there's a toggle button to enable/disable this. So, if the user chooses to not use DEM then this option will be kept inactive…

  • RE: ADS8885: have a louder noise than competitor device

    Actually customer want use our device p2p replace the AD7691. So they use almost the same schematic. For customer, thay didn't make test about SNR or THD, they make a test about the whole machine. They found the machine output with a jitter. I talk…

  • RE: PROCESSOR-SDK-J721E: SBL for HLOS sd card fails in SCI client

    Resolved
    Hi Pablo, Sorry if I was not clear in my previous post. I am able to reproduce the error when running the app in TX only mode. The loop-back mode works fine on my end, so if you do not have a specific requirement for TX only mode, you can move ahead with…

  • RE: TDA4VM: Eglimage failed to bind to other process dmafd

    Hello Nikhil In a single test program for one process, the only "1b, 3" process is working normally, so I want to first verify it through the "1b -> 2 -> 3" test program 1. When you use 1a -> 2 -> 3, this works fine right?…

  • RE: LMP7707: The effect of the photodiode dark current and the op amp's own bias current on the op amp integration circuit

    Hi Raymond it's so kind of you ,thanks We have similar ideas ，so I'm going to make a Evaluation board to verify three circuit like IVC102/two PDs and OPA subtractor/r everse biase the PD. But how to reverse biase the PD? I make a circuit like below…

  • RE: MSP430FR2672: Shielding for CapTIvate

    Resolved
    Hi Kei, For both FDC1004 and MSP430 Captivate MCUs, actively driven shields will be helpful, but may not be needed in every case. Active shields are used rarely in Captivate HMI applications, buth they do help in reducing the large parasitic capacitances…
