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.
The LC7536LHS operates from 5 V and 10 V supplies and
is available in 30-pin DIPs.
Features
• Three-line serial control.
• Two device select.
• Tap at 20 dB attenuation for a loudness control.
• 80 dB attenuation range adjustable in 1 dB steps.
• 96 dB maximum attenuation.
• 75 dB crosstalk rejection.
• 0.022% total harmonic distortion.
• 47kΩ input impedance.
• 5 V and 10 V supplies.
• 30-pin DIP.
