DESCRIPTION
The OPA1611 (single) and OPA1612 (dual)
bipolar-input operational amplifiers achieve very low
1.1nV/√Hz noise density with an ultralow distortion of
0.000015% at 1kHz. The OPA1611 and OPA1612
offer rail-to-rail output swing to within 600mV with a
2kΩ load, which increases headroom and maximizes
dynamic range. These devices also have a high
output drive capability of ±30mA.
These devices operate over a very wide supply range
of ±2.25V to ±18V, on only 3.6mA of supply current
per channel. The OPA1611 and OPA1612 op amps
are 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.
Both the OPA1611 and OPA1612 are available in
SO-8 packages and are specified from –40°C to
+85°C. SoundPlus ™
