10 MHz gain-bandwidth, 9V/µs slew rate — signal chain fit
The NE5532AD: Its 10 MHz gain-bandwidth product and 9V/µs slew rate suit it for audio preamplification, active filters, and general signal conditioning where the signal frequency stays within the GBW ceiling and the output swing does not exceed the slew-rate limit at the target frequency. Drawing 8 mA total for both channels, the supply current per amplifier is 4 mA — a reasonable budget for a dual op amp in this performance class.
DC accuracy and output drive
The 38 mA output current per channel can drive moderate loads such as a 600 Ω audio line or the input of a successive-approximation ADC without an external buffer.
