GENERAL DESCRIPTION  
The SSM2160 and SSM2161 allow digital control of volume of  
six and four audio channels, respectively, with a master level  
control and individual channel controls. Low distortion VCAs  
(Voltage Controlled Amplifiers) are used in the signal path. By  
using controlled rate-of-change drive to the VCAs, the “click-  
ing” associated with switched resistive networks is eliminated in  
the Master control. Each channel is controlled by a dedicated  
5-bit DAC providing 32 levels of gain. A master 7-bit DAC  
feeds every control port giving 128 levels of attenuation. Step  
sizes are nominally 1 dB and can be changed by external  
resistors. Channel balance is maintained over the entire master  
control range. Upon power-up, all outputs are automatically  
muted. A three- or four-wire serial data bus enables interfacing  
with most popular microcontrollers. Windows* software and an  
evaluation board for controlling the SSM2160 are available.

The SSM2160 can be operated from single supplies of +10 V to  
+20 V or dual supplies from ±5 V to ±10 V. The SSM2161 can  
be operated from single supplies of +8.5 V to +20 V (for  
automotive applications) or dual supplies from ±4.25 V to  
±10 V. An on-chip reference provides the correct analog  
common voltage for single supply applications. Both models  
come in P-DIP and SO packages. See the Ordering Guide for  
more details.
