The NE5532 was developed and originally marketed by Signetics in 1979. This component was widely used in many applications due to its low noise and high Absolute Maximum Operating Voltage of 44VDC. It has been designed in countless applications at Otari, ADM and others operating at 40VDC.
The part is still in production at several semiconductor suppliers.
A major supplier of the NE5532 has recently reduced the Absolute Maximum Operating Voltage to 36VDC.
This is of great concern as when a NE5532 is replaced in legacy applications it will be operating beyond its new operating voltage.
There are certainly modern parts which will operate at 44VDC, but replacing a legacy application with a 'new' NE5532 will be destined to failure.
Shouldn't the supplier change the part number to avoid this potential failure issue?
