NJM2172V

The NJM2172V is a dual operational amplifier (op-amp) from New Japan Radio (NJR), designed for high-performance audio applications. Key features include:
- Low noise (5.5nV/√Hz) and low distortion (0.0005%), ideal for audio signal processing.
- Wide supply voltage range (±2V to ±18V), supporting flexible power configurations.
- High slew rate (10V/µs) and wide bandwidth (10MHz), ensuring fast signal response.
- Built-in mute function, allowing smooth audio switching.
Common applications include preamplifiers, active filters, and audio mixers. Its dual-channel design saves board space, while its low power consumption enhances efficiency.
For detailed specs, refer to the NJM2172V datasheet.
