The TLO72 has extremely little load driving capability, is prone to latching up if the inputs are overloaded, and has a slew of other "features" that make it unsuitable for audio.
The NE5532 outperforms the TLO72 in almost every aspect of audio application, with the only significant exception being the 5532s' unusually large input current requirement.
Operational Amplifier, 2 Func, 6000uV Offset-Max, BIPolar, PDIP8, 0.300 INCH, PLASTIC, DIP-8 The Op-Amp also has a low range operating voltage from ☓V to ☒0V and hence can be used in wide variety of voltage ranges.Operational Amplifier, 2 Func, 20000uV Offset-Max, BIPolar, PDSO8, PLASTIC, SO-8 Since the IC is highly immune to noise it is commonly preferred in sensitive audio signal conditioning designs. The gain of the IC is upto to 5000 and hence is commonly used in audio pre-amplifier circuits. The IC features a very low noise with unity gain internal compensation. The NE5532 is a Low Noise Audio amplifier IC form Texas Instruments. Available packages: TO-99, CDIP, DSBGA, SOIC, PDIP, DSBGA.Common Mode rejection ratio (CMRR): 100dB.Dual Low Noise Op-Amps in a single package.NE5532 Dual Op-Amp IC features and specifications The Op-Amp is internally compensated for high unity gain with maximum output swing bandwidth, low distortion and high slew rate. The NE5532 is a Dual Low Noise Op-Amp in 8-pin package commonly used as amplifiers in audio circuits for its noise immunity and high output drive capability.
