Automotive low power precision audio operational amplifier

The OPA1612-Q1 device from Texas Instruments is a dual, SoundPlus, bipolar-input operational amplifier that achieves achieve very low 1.1nV/√Hz noise density with an ultralow distortion of 0.000015% at 1kHz. The OPA1612-Q1 device offers rail-to-rail output swing to within 600mV with a 2kΩ load, which increases headroom and maximises dynamic range. 

These devices also have a high output drive capability of ±30 mA. These devices operate over a very wide supply range of ±2.25 V to ±18 V, on only 3.6 mA of supply current per channel. The OPA1612-Q1 op amp is unity-gain stable and provide excellent dynamic behaviour over a wide range of load conditions.

The dual version features completely independent circuitry for lowest crosstalk and freedom from interactions between channels, even when overdriven or overloaded.

The OPA1612-Q1 device is available in a SOIC-8 package. The device is specified from -40 to +125°C.
