High-Voltage, Two-Channel

Electronic Attenuator

Overview

The LC7536LHS is a two-channel electronic attenuator for

volume, balance and loudness controls in stereo audio ap-

plications.

The LC7536LHS reads data from a three-line serial bus to

control attenuation in 1 dB steps over an 80 dB range, up to

a maximum of 96 dB. It features a center tap at 20 dB at-

tenuation for a loudness control using a minimum of exter-

nal components. A device select pin allows two devices to

be connected to the serial bus.
