OPA2134 vs NE5532

Overview of OPA2134

The OPA2134 is a low-noise, ultra-low distortion operational amplifier designed for high-quality audio applications. The OPA2134 has a FET input stage that delivers excellent sound quality and high-speed response, so it's great for audio applications. It's got a powerful output drive capability and excellent DC characteristics, so it's suitable for a variety of demanding applications. It also supports a wide output swing (only 1V from the power supply rails) for greater dynamic range, making it ideal for use in a wide range of audio circuits.

You can get the single- and dual-channel versions in 8-pin DIP or SO-8 surface-mount packages, while the quad-channel version is available in a 14-pin DIP or SO-14 surface-mount package. The devices operate over the -40°C to 85°C temperature range and can be designed and analyzed using SPICE macro models.

Overview of NE5532

The NE5532 series operational amplifiers are high-performance devices that combine excellent DC and AC characteristics. They have low noise, high output drive capability, high open-loop gain, maximum output swing bandwidth, low distortion, high slew rate, built-in input protection diodes, and output short-circuit protection. These amplifiers are internally compensated to support stable operation in unit gain conditions. In addition, these devices are limited to a maximum equivalent input noise voltage.
