The Texas Instruments OPA604AU is a FET-input operational amplifier engineered for superior AC performance, making it ideal for high-fidelity audio systems and other applications demanding excellent dynamic characteristics. It boasts very low harmonic distortion, achieved through advanced circuit techniques and laser trimming, resulting in exceptional sound quality.
Key electrical specifications include a gain bandwidth product of 20 MHz and a high slew rate of 25 V/µs. The amplifier operates over a wide supply voltage range of ±4.5 V to ±24 V and can drive a 600 Ω load. With a typical voltage noise density of 11 nV/√Hz at 1 kHz and a low total harmonic distortion plus noise of 0.0003% at 1 kHz, the OPA604AU ensures clean signal amplification.
This operational amplifier features a FET input architecture and is unity-gain stable. It has a maximum offset voltage of 5 mV at 25°C and a typical quiescent current of 5.3 mA per channel. The device is housed in a SOIC package and operates within a temperature range of -40°C to 85°C.
Applications for the OPA604AU include professional audio equipment, PCM DAC I/V converters, spectral analysis equipment, active filters, transducer amplifiers, and data acquisition systems.
The OPA604AU operates from a single supply of 9V to 48V or dual supplies of ±4.5V to ±24V.
The OPA604AU is available in an 8-pin SOIC (D) package.
The operating temperature range is -40°C to 85°C.
The typical gain bandwidth product is 20 MHz.
The typical slew rate is 25 V/µs.
The maximum input bias current is 200 pA.
The typical THD+N at 1 kHz is 0.0003%.
