NE5534P
NE5534P - 30V, 10MHz Low-Noise Op Amp | Texas Instruments
The Texas Instruments NE5534P is a single, low-noise operational amplifier designed for audio applications, with a 30 V supply rating, 10 MHz typical unity-gain bandwidth, and an 8-pin PDIP package. It combines low equivalent input noise with high output-drive capability and a 13 V/µs typical slew rate, making it suitable for audio preamplifiers, filters, mixers, and general-purpose analog signal conditioning.
An operational amplifier is an analog integrated circuit that uses high-gain differential amplification to increase a voltage difference between its input terminals. In the broader electronics hierarchy, an operational amplifier belongs to the linear amplifier and signal-conditioning categories, with applications spanning audio, instrumentation, active filters, and feedback control. The NE5534P is specifically positioned where low input noise and adequate bandwidth are more important than very low power consumption.
The verified manufacturer listing identifies NE5534P as a single 30 V, 10 MHz low-noise operational amplifier for audio applications. The supplied search data also identifies a 13 V/µs slew rate, a 3.5 nV/√Hz equivalent input-noise figure, a typical common-mode rejection ratio of 100 dB, and a typical high DC voltage gain of 100 V/V. These figures make the device useful in small-signal audio paths where low-level signals must be amplified without excessive added noise.
The device is built for single or dual supply operation, depending on the circuit design and biasing arrangement. Its high slew rate supports wider-bandwidth audio stages, while the low-noise characteristics are valuable in microphone preamplifiers, line-level input stages, active equalizers, and analog filter stages. Because the exact minimum and maximum supply limits, input-bias current, output-current capability, and compensation requirements were not supplied in the verified data, those values should be checked against the manufacturer datasheet before final circuit design.
Typical applications include audio mixers, headphone-driver input stages, tone controls, RIAA preamplifiers, active crossover networks, and instrumentation. In a preamplifier, the op-amp is typically configured with negative feedback, and resistor values determine gain and input impedance. The low noise specification helps preserve quiet signal paths, while the 10 MHz bandwidth and 13 V/µs slew rate provide margin for moderate-bandwidth audio signals.
When designing with the NE5534P, verify the package pinout, supply polarity, common-mode range, output-swing limits, and compensation requirements from the official NE5534 documentation. Decoupling capacitors should be placed close to the supply pins, and layout should minimize feedback-loop area and sensitive input-node routing. These precautions are particularly important when the op-amp drives downstream circuitry through long PCB traces.
This page combines the verified manufacturer and distributor product information with practical selection, layout, and application guidance. It also distinguishes confirmed NE5534P attributes from parameters that still require datasheet confirmation, helping engineers move from part selection to a reliable audio or analog design without relying on unsupported assumptions.
