OPA1679IRUMT TI Instrumentation, OP Amps, Buffer Amps

The OPA1679 is a quad low-noise operational amplifier designed specifically for audio applications, operating from 4.5V to 36V single supply (or ±2.25V to ±18V dual). It achieves low distortion (0.0001% THD+N) and low noise (4.5nV/√Hz). The device features rail-to-rail output swing with 16MHz gain-bandwidth product and 9V/µs slew rate. Each amplifier consumes 1.5mA supply current. Rail-to-rail output maximizes dynamic range. Selection is the primary choice for professional audio applications requiring multiple amplifiers. Applications include microphone preamplifiers, headphone amplifiers, active filters, and digital-to-analog converter (DAC) output buffers in studio equipment, mixing consoles, and high-fidelity consumer audio.
