  • OPA2863: Power-down feature question

    TI Thinks Resolved
    Part Number: OPA2863 Dear TI: I am using part number OPA2863RUNR as a buffer amplifier. This amp features a power-down pin. The amplifier IC package is powered with 5VDC. I am observing that when the power-down pin is above 3.9VDC the output buffer follows…

  • RE: OPA2863: AC PSpice Simulation for Stability + Monte Carlo

    Hi Anthony, I am reconnecting with you via email to set up a call to finalize your circuit and resolve the discussion. I'll post a generalized update here for anyone on the forum who need's advice on stabilizing their circuit. TI resources do…

  • RE: LMH6622: LMH6622

    Hi, You could consider using the lower power OPA2863 . This is a 50 MHz, RRIO, voltage feedback amplifier with 2.7 - 12.6 V supply voltage capability. The unity-gain stable OPA2863 consumes only 700 uA per channel and is offered in a very small 2x2mm…

  • RE: LM393: Schematic circuit verification.

    Hi all, I recently found a new IC OPAx863A with dual op-amp and I tried to design the peak detector circuit as below but I am struggling to obtain a peak amplitude. Can anyone help me to resolve the issue? Kindly note that I would like to operate this IC…

  • Understand the working of OPA2810 as a buffer

    Part Number: OPA2810IDGKR Hi TI, We are looking for an alternate to OPA2863. We came across OPA2810 which has required slew rate and package with pin to pin matching. What my query is how is it different from OPA2863. Can I use it as a buffer for a…

  • RE: TLV3502-Q1: The window comparator circuit block is giving voltage dips at input as well as at the output during hysteresis region

    Resolved
    Hi Rajat, I see two issues: 1. A resistor in the feedback loop of the fast OPA2863 wired as voltage follower is no good idea. This can cause stability issues. So either you reduce this resistor to zero or you add a phase lead capacitance to restore the…

  • RE: OPA863: Inquiry on the total delay time to achieve 90% of Vcc
