  • OP07: OP07 burn out,

    TI Thinks Resolved
    Part Number: OP07 Tool/software: HI Raymond below IC 4 which use the old date code work is ok, but change to new date code , the op 07 output will down to -0.7V when LOC111 output 0~5v swap and the op07 surface very hot. i think maybe is the D2…

  • OP07: verify it is genuine component

    Part Number: OP07 Hi TI, Venture had bought OP07CDR from TI. But now Venture had found issue on new date code that meanufactor on year 2025 . Pls help to verify is the below picture marking that show is genuine component. , NG IC: Regards

  • OP07: op07c Impedance symmetry issue

    TI Thinks Resolved
    Part Number: OP07 Op07c pins 4 and 7 are connected to V++5V and V - GND, respectively. Pin 1 and pin 8 are suspended. Measure the GND voltage of 1 and 8 pairs respectively. Should they be similar values? The measurements I am currently taking are 4V for…

  • OP07: Abnormal

    TI Thinks Resolved
    Part Number: OP07 Tool/software: During production, an abnormal phenomenon occurred on a batch of motherboards after power-up. The same batch of motherboards used two different printed OP07 chips, and the problematic ones were from the same batch of OP07…

  • OP07：Abnormal

    Part Number: OP07 Tool/software: 在生产过程中，电源后的一批主板上发生了异常现象。同一批主板使用了两种不同的印刷OP07芯片，而有问题的主板来自同一批OP07。其背后的原则如下： ‌图1示意图 1.有缺陷的芯片被识别为同一传入批次的一部分，标有丝网码‌“ 52m” ‌（如下所示）。 图 2 2.在此电路中，OP07芯片总共使用5个销钉，销1、5和8左浮动：引脚4：电源（-15V）引脚7：电源（+15V）引脚3：接地这三个引脚显示正常的电压水平…

  • OP07: Batch replacement caused output anomalies

    TI Thinks Resolved
    Part Number: OP07 We have been using OP07C for more than 3 years. The OP07C purchased from Arrow in August 2025 had abnormal output, but the OP07c purchased in 2024 had normal output. The circuit diagram is shown below. We would like to know if the device…

  • OP07: looking for output impedance value

    TI Thinks Resolved
    Part Number: OP07 Tool/software: Hi team, May I learn from you about output impedance value of OP07CP? I have check the value is 60-ohm, but cannot find it from device datasheet. Please help to confirm it, thanks. Regards, Ben

  • OP07: OP07CDR current consumption

    TI Thinks Resolved
    Part Number: OP07 Tool/software: What is the variation in current consumption? When replacing the OP07CDR with a different lot, the current consumption of the part will go from 5mA to 2mA. Is it really that variable? This is the result of only replacing…
