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.
