CMOS IC
LC7535M
Electronic Volume/Loudness Control with Serial Data
Control and High Voltage-Handling Capacity
Overview
The LC7535M is an electronic volume and loudness
control IC that provides volume, balance, and loudness
functions with a minimal number of external components
and that can be controlled electronically.
Feature
鈥?High voltage-handling capacity: 鹵16 V.

Functions
鈥?Volume: Provides 81 positions from 0 dB to 鈥?9 dB in
1-dB steps and 鈥撯垶. A balance function can be
implemented by controlling the left and right volume
levels independently.
鈥?Loudness: A loudness function can be implemented by
attaching external capacitors at the output tap provided
at the 鈥?0-dB position in the 5-dB step volume control.
鈥?S (select) pin: Up to two LC7535M chips can be used on
the same bus.
鈥?Serial data input: The LC7535M supports
communication with the controller in the CCB format.
鈥?CCB is a trademark of SANYO ELECTRIC CO., LTD.
鈥?CCB is SANYO鈥檚 original bus format and all the bus
addresses are controlled by SANYO.
