Key parametric decisions for the BOM
The 10 MHz GBW sets the closed-loop gain-bandwidth trade-off: a gain of 10 gives a 1 MHz small-signal bandwidth. Input bias current is 500 nA typical, and offset voltage is 500 µV, both adequate for non-precision DC applications but not for microvolt-level amplification. The single-channel configuration (one op-amp per package) simplifies routing in mixed-signal boards where isolation between channels matters.
Lifecycle reality: obsolete and how to source it
The NE5534D is officially obsolete. There is no listed successor or last-time-buy date in the record.
The 8-SOIC package (0.154-inch body width, 3.90 mm) uses a standard SOIC-8 land pattern. It is supplied in Tube form. The surface-mount footprint is compatible with most automated assembly lines. No exposed pad — thermal management relies on the copper pour area on the PCB.
