[Condition] IC and adapter was all brand new.

[Modular Type] The 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 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.

This is dual op only V31 modular.

V31: SOIC to DIP: Change package only.

[IC Place of Origin] Randmon

[Production Date] Randmon

V5 and V31 (version 2022) series is the fifth generation adapter board. The V series has been produced since 2018. It is a high-quality adapter designed and manufactured by me.

* It adopts the top PCB technology, 4oz copper foil, 2.0mm PCB thickness, FR4 material, full smooth edges and corners, made by China's first-class PCB Factory.(You can view the photo detection report.)

* The connector is customized by high quality factory, 5U" gold plated.

* It is made of 3.8% Ag EDSYN solder wire.

We are a very well-known seller of HiFi electronic components in China.

It is no exaggeration to say that what we manufacture is the best HiFi operational amplifier adapter in China.And we have insisted on selling only original chips for 19 years.
