The 5532 is a dual 5534 with compensation set internally for unity-gain stability.
The major features are:
The bipolar input devices give their best noise performance at low to medium impedances, in the range 100 - 1000 Ohms. In virtually all audio applications the 5532 will be quieter than the TL072.
Bipolar input devices, with significant bias and offset currents.
The common-mode range of the inputs is a healthy +/-13V, with no phase inversion problemsif this is exceeded.
The input pins are tied together with diodes for reverse-Vbe protection. This is normally unnoticeable in audio use, but it does mean the 5532 makes a poor comparator.
Very low, though not quite zero, THD levels. THD still depends on how heavily the output is loaded.
Higher power consumption: approx 4mA per opamp section. The DIL version runs perceptibly warm when quiescent on +/-15V rails.
Requires proper rail decoupling near the chip.
