High-
Voltage, Two-Channel Electronic Attenuator
Overview
The LC7536LHS is a two-channel electronic attenuator for volume, balance and loudness controls in stereo audio applications.
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 attenuation for a loudness control using a minimum of external components. A device select pin allows two devices to be connected to the serial bus.
