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.
