• Manufacturer Part Number: lc75396ne
• Description: Single-chip Electronic Volume Control System
• Manufacturer: Sanyo Semiconductor Corporation

Usage Notes
• When the power is first applied, the internal analog switches are in indeterminate states. The chip therefore requires
• After power is first applied, applications must initialize this chip by sending the initial data (1) and (2) described below.
• Provide grounding patterns or shielding for the lines to the CL, DI, and CE pins so as to prevent their high-frequency
muting or other external measures until it has received the proper data.
digital signals from interfering with the operation of nearby analog circuits.
Initial data ...
After transferring that data, set the left and right channel initial settings before turning off the mute function.
