The NE5534AP is an operational amplifier (op amp) from the NE5534A family. It has high output current, low input offset voltage, low noise and distortion, and temperature stability. The typical operating temperature range is from -40 °C to +125 °C. It is ideal for applications such as audio amplifiers, line receivers, servo amplifiers, buffered vertical deflection in TVs, instrumentation amplifiers, charge amplifiers, intergrators, sample and hold circuits, very low noise amplifiers, low distortion amplifiers and line drivers.

The NE5534AP is a dual high-performance low-noise operational amplifier with automotive temperature range and high gain. It offers a wide supply voltage range from 4.0V to 30V and can provide a maximum output current of 320mA. An internal ESD protection circuit ensures stability and reliable operation. Its high open-loop gain and low noise level makes it ideal for use in many applications, especially in audio applications. It has excellent stability across the supply voltage range and wide temperature range. It is also suitable for low-noise applications, such as medical equipment or instrumentation circuits.

The working principle of the NE5534AP is based on the simple non-inverting amplifier configuration. The non-inverting terminal of the op amp is connected to a fixed direct current bias voltage source. This bias voltage divides the input signal into two equal voltages that are applied to the input terminals. The output voltage Vout is amplified by the gain of the op amp, which is determined by the ratio of the two resistors R1 and R2 connected externally to the op amp. This voltage Vout is given by the equation: Vout = Vi (1 + R1/R2), where Vi is the input voltage applied across the input terminals of the op amp. Thus, the gain of the circuit is set by the ratio of the two resistors.

The NE5534AP is often used in audio applications such as speaker amplifiers, power amplifiers, microphone amplifiers, and line drivers. It has a slew rate of 0.5V/µs and a maximum supply voltage of 30V. This means that it can supply a large amount of current to a load without producing any distortion or noise. It can also be used in instrumentation applications, such as pressure sensors and transducers, as it offers high accuracy and low current consumption. Additionally, it can be used in buffered vertical deflection in TVs, as it offers excellent image quality.

The NE5534AP is an excellent choice for a variety of applications due to its stability and low noise characteristics. Its wide supply voltage range makes it suitable for a variety of low-voltage and high-voltage applications. Additionally, its low input offset voltage special characteristics make it suitable for precision instrumentation circuits. Its high output current and low distortion also make it suitable for audio applications.
