TLV2374: Unity gain stable?

David Strand

Part Number: TLV2374

Is TLV2374 unity gain stable or not? I e can I connect it as a follower with gain = 1 and it is stable? I should be able to determine this myself if I think about it, but most OP amp datasheets say either "unity gain stable" or "stable if gain > x dB"

    Hi David,

    Yes, it is unity-gain stable. Please refer to the phase and gain margin information in the data sheet. An additional clue is that the slew rate (SR) is specified '...at unity gain'. Finally, you'll notice in Figure 16 that the gain appears to be to cross 0dB at a constant 20dB/decade, which ultimately yields plenty of phase margin. The gain plot of decompensated amplifiers will start to roll off at greater than 20dB/decade before unity gain (0dB). Here is an article that you may find helpful:

    On a side note, you may find the TI Precision Labs video on bandwidth interesting. Here is the link:
