How to query the model from the code of the operational amplifier chip??

I dissected an audio dual-operation amplifier without a model and packaged as sop-8. After carefully checking the chip, I saw the unique code: T544 A, but I couldn't find this model. Can you help me

I use this audio Opamps for decoding, the front stage, but somehow the model has been polished.

What is a difference between an operational amplifier and instrumentation amplifier and can you use one opamp to perform a same task as 3 opamp instrumentation amplifier?

An op amp is made from transistors, resistors and capacitors. It is enclosed in a "chip". A basic instrumentation amp is made of 2 op-amps. you can't have a single op-amp perform as good as a instrumentation amp, although it can perfrom the same task. An i-amp has much better CMMR (common-mode rejection) and a higher input impedance.


Why is the MC1458 IC used?

Answer The MC1458 is a high-performance operational amplifier with highopen-loop gain, internal compensation, high common-mode rangeand exceptional temperature stability. The MC1458 is short-circuitprotected. The MC1458/SA1458/MC1558 consists of a pair of 741 operationalamplifiers on a single chip.
