3 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.
