OPA1612-Q1 (ACTIVE)

Automotive, 1.1nV/√Hz Noise, Low Power, Precision Audio Operational Amplifier

 

Description

The OPA1612-Q1 device is a dual, SoundPlus, bipolar-input operational amplifierthat achieves achieve very low 1.1-nV/√Hz noise density with an ultralow distortion of 0.000015% at 1 kHz. The OPA1612-Q1 device offers rail-to-rail output swing to within 600 mV with a 2-kΩ load, which increases headroom and maximizes 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 behavior 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°C to +125°C.

For all available packages, see the orderable addendum at the end of the datasheet.
