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.
The LC7536LHS operates from 5 V and 10 V supplies and
is available in 30-pin DIPs.
