OPA1664AIPWR Description

Short technical summary and product information.

The Texas Instruments OPA1664AIPWR is a quad-channel, bipolar-input SoundPlus audio operational amplifier. It is engineered for high-fidelity audio applications, delivering a low noise density of 3.3nV/√Hz at 1kHz and an ultra-low distortion of 0.00006% at 1kHz.

This op amp features a wide supply voltage range from ±1.5V to ±18V or 3V to 36V, and a gain bandwidth of 22MHz. Its rail-to-rail output capability increases headroom, maximizing dynamic range. The device operates within an ambient temperature range of -40°C to 85°C.

Available in TSSOP-14 and SOIC-14 surface-mount packages, the OPA1664AIPWR is suitable for various audio circuitry designs. Its low quiescent current of 1.5mA per channel and high slew rate of 17V/µs make it an efficient choice for demanding audio systems.
