Description
The AV112-12 is a low-distortion, PIN diode variable attenuator in a small SOIC-8 package. The design is based on Skyworks unique series of HIP3TM components. The AV112-12 consists of a monolithic quadrature hybrid and a matched pair of PIN diodes designed for low-distortion attenuators. AV112-12LF is packaged in a lead (Pb)-free, fully RoHS-compliant SOIC-8 package and is electrically identical to AV112-12.

Performance is guaranteed only under the conditions listed in the specifications table and is not guaranteed under the full range(s) described by the Absolute Maximum specifications. Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty.
CAUTION: Although this device is designed to be as robust as possible, ESD (Electrostatic Discharge) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions must be employed at all times.
