OPA1611AID General 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 OPA1612 offer 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 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 SOIC-8 packages and the OPA1612 is available in SON-8. These devices are specified from –40°C to +85°C.

I order a second time. The quality is good, the sound is also excellent, only you need to put a fee so that the phone was in the area of the meter maximum.

Holes in the box does not fit perfectly with my board, so cannot use all screws. But maybe it's the PCB, not the enclosure.

J**n 02/24/2021

Diodes went a little more than a month to krasnoyarsk, the voltage drop is normal (2.7 v at 30ma), in the tv has not yet put, took in a black package.
