MC3340

Order this document by MC3340/D Electronic Attenuator The MC3340 is a simple but very effective electronic attenuator. This device 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 include instrumentation control, remote control audio amplifiers, electronic games, and CATV (cable TV) set–top converter audio control.
