Introducing the Texas Instruments OPA1664 Audio Operational Amplifier

The OPA1664 from Texas Instruments represents a significant advancement in audio signal amplification, offering exceptional sound quality and performance for a wide range of audio applications. This high-fidelity operational amplifier is designed to meet the demands of audiophiles and professional audio equipment manufacturers alike.

At the heart of the OPA1664 is Texas Instruments' advanced SoundPlus™ technology, which ensures ultra-low distortion and noise levels, resulting in a pristine audio signal that captures every nuance of the original recording. With a typical total harmonic distortion plus noise (THD+N) of 0.0001% and an ultra-low noise density of 2.8 nV/√Hz at 1 kHz, this op-amp sets a new standard for audio purity.

The OPA1664 operates over a wide supply range from ±2.25V to ±18V, providing designers with the flexibility to use it in various circuit configurations. Its rail-to-rail output swing ensures maximum dynamic range, making it an excellent choice for driving high-performance audio converters in both single-ended and differential configurations.

Featuring a high slew rate of 10 V/µs and a wide bandwidth of 11 MHz, the OPA1664 can handle a broad spectrum of audio frequencies without sacrificing clarity or detail. This makes it an ideal choice for high-end audio equipment, including headphone amplifiers, mixing consoles, preamplifiers, and studio monitors.

Moreover, the OPA1664 is available in a compact 14-pin TSSOP package, allowing for space-saving designs without compromising on audio quality. Its robust design also ensures reliable performance over a wide temperature range, making it suitable for both consumer and professional audio applications.

For designers and audiophiles looking to elevate their audio systems to the next level, the OPA1664 from Texas Instruments offers the perfect blend of high fidelity, versatility, and performance. Experience audio reproduction as it was meant to be heard with this state-of-the-art operational amplifier.
