The attenuator requires external DC blocking capacitors, positive supply voltage (VS) and four individual positive control voltages (V1–V4). The AA264-87 is particularly suited where high attenuation accuracy, low insertion loss and low intermodulation products are required. Typical applications include base station, wireless data and wireless local loop gain control circuits.

Exceeding any of the absolute maximum/minimum specifications may result in permanent damage to the device and will void the warranty. Refer to the “Recommended Solder Reflow Profile” Application Note. 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. Tape and Reel Information TSSOP-16 VHIGH = 3 to 5 V (VS = VHIGH ± 0.2 V).
