❒ DESCRIPTION
The OPA1611 (single) and OPA1612 (dual) bipolar
-input operational amplifiers achieve very low
1.1
-nV/√Hz noise density with an ultralow distortion of
0.000015% at 1 kHz. The OPA1611 and OPA1612offer rail
-to
-rail output swing to within 600 mV with a2
-kΩ load, which increases headroom and maximizesdynamic range. These devices also have ahighoutput drive capability of ±30mA.
These devices operate over a very wide supply rangeof ±
2.25V to ±18V,on only
3.6mA of supply currentper channel. The OPA1611 and OPA1612 op ampsare unity
-gain stable and provide excellent dynamicbehavior over a wide range of load conditions.
The dual version features completely independentcircuitry for lowest crosstalk and freedom frominteractions between channels, even when overdrivenor overloaded.
Both the OPA1611 and OPA1612 are available inSOIC
-8 package and the OPA1612 is available inSON
-
8. These devices are specified from –40°C to+85°C.
