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.

• Designed for use in:

DC Operated Volume Control

Compression and Expansion Amplifier Applications

• Controlled by DC Voltage or External Variable Resistor

• Economical 8–Pin Dual–In–Line Package
