Description
The Texas Instruments NE55LP (not NE55P) is a dual, low-noise operational amplifier designed for audio applications. It features a high common-mode rejection ratio (CMRR), low noise gain, and a wide operating temperature range. The device operates from ±2 to ±12 V power supplies and has a maximum frequency of 10 MHz.
The NE55LP is suitable for preamplifiers, tone control circuits, and audio mixers in professional audio equipment. Its high CMRR and low noise gain make it ideal for applications where electromagnetic interference (EMI) is present. The device also finds use in instrumentation amplifiers, active filters, and voltage regulators.
In summary, the NE55LP is a dual operational amplifier designed for high-performance audio applications that require low noise and high common-mode rejection ratio.
