Product Summary

The MC3340P is a simple but very effective electronic attenuator. The MC3340P offers up to 80 dB of attenuation control for frequencies to 1.0 MHz. THD (distortion) is less than 1% up to 15 dB attenuation and less than 3% up to 40 dB. Typical uses of MC3340P include instrumentation control, remote control audio amplifiers, electronic games, and CATV (cable TV) set-top converter audio control.
