Original question:

NE5532: Single supply operation specification

NE5532: Specification chage

Part Number: NE5532
Other Parts Discussed in Thread: OPA828, OPA1611, LM4562

Hello

As of December 2025 you have significantly modified the specification of the NE5532. Most significant is reducing the maximum rail voltage from +/-22V to +/-18V. In addition you have reduced the slew rate from 9V/us to 5V/us.

How are we as product designers and current designs going to cope with power lines at +/-21V, and need 9V/us?

And candidly how can you use the same part number for a product whose specification is nothing like it has been for decades?

Regards

Dr Craig Sawyers

    Hello, 

    This change originated with a product change notification on November 15, 2023, related to the Fab facility transition from SFAB (150mm) to RFAB (300mm). The redesigned device generally meets or exceeds the original specifications. In cases where a specification could not be met, the specification was revised. Typical values, such as slew rate, were also updated to reflect these changes. Following customer feedback, we are updating datasheets to clearly indicate differences between the original and redesigned die. The datasheet specifications currently cover both the original and redesigned parts, as both will be available until existing inventory is depleted.

    The recommended supply use to be +/-15V while the old absolute maximum use to be +/-22V. The new abs max was adjusted to highlight the change to the new part based on the Fab change. +/-21V is outside the recommended voltage range for both the old and the new. 

    We do understand the impact this is having and are taking feedback seriously.

    I am sorry but that does not wash. The specification of the NE/SE5532(A) has been stable since its introduction in 1979 by Signetics. It is the professional and domestic audio mainstay.

    There is even a Wikipedia page about it, which makes particular mention of the 44V abolute max, and 9V/us slew rate.

    You guys at TI make some landmark opamps; OPA828/2828, OPA1611/12 and LM4562. But these are typically an order of magnitude more expensive than the NE5532. You cannot seriously expect engineers (or accountants) to conisder opamp parts costs by a factor of 10?

    Anyway, ONSEMI are still making them to the original spec, so that is where I will be headed for real NE/SE5532(A)'s
