LC7536M
Function
• 5-dB step attenuator inputs
These inputs must be driven by low-impedance circuits.
• Loudness circuit connections
Connect high-band compensation capacitors between the
CT1 and 5dBIN pins, and connect low-band compensation
capacitors between the CT2 and VM pins.
• 5-dB step attenuator outputs
These signals should be received by loads of about 47 kΩ
to 1 MΩ.
• 1-dB step attenuator inputs
These inputs must be driven by low-impedance circuits.
• 1-dB step attenuator outputs
These signals should be received by loads of about 47 kΩ
to 1 MΩ.
• Common pins for the volume controls. The printed circuit
board pattern for these pins should be designed to have as
low an impedance as possible. Since LVM, RVM, and VSS
are not connected internally in the IC, they may be
connected to separate external circuits that meet their
individual specifications.
Since the capacitors between the VM pins and the power
supply when a single power supply is used become the
residual resistance components at maximum attenuation,
care is required in determining the values of these
capacitors.
• Selects the address code of data during formatted.
When this pin is connected to VDD, the IC accepts data
when the address code is 9, and when connected to VCC,
it accepts data when the address code is 8.
• Inputs for the serial data that controls the IC. The input
signals must have an amplitude of 0 to 5 V.
• Power supply connections. These pins must be connected
to the corresponding power supply. Applications must be
designed so that VCC is not applied before VDD.
• Unused pins. These pins must be left open.
