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.
