Identify this component... Code 33x1

[ForeverLearningJP]

Good day everyone, I have an ic to identify. It is an smd package with 5 pins. Used in an active audio circuit and named u1 of the circuit. It has a marking on it, 33x1 but no search turned out successful. However I do have a drawing of the circuit to help understand the pins and a picture of the component as well as a possible matching datasheet for an exact or similar IC (http://www.ti.com/lit/ds/symlink/lm321.pdf). This can be confirmed or a new IC datasheet can be presented that matches my circuit. All help is appreciated. Thanks in advance.

From the circuit traced, I would think that the IC's basically an Op Amp with Terminals, starting with B- and clockwise, + input, +V, Output, - Input.
Any good Audio Op Amp should fit in here. The best being, maybe, LT1115.

I searched up the LT1115 but i am not seeing an sot-23 package version of it......

I can't find a reference to 33X1, however the device is clearly an op-amp (or something with the same set of inputs and outputs). It is not a comparator because there is no pull-up on the output.

I concur with @ramussons
