The MX029 Digitally Controlled Amplifier Array replaces audio level controls in radio and wireline communications applications. It is a single-chip LSI circuit comprised of two discrete, digitally controlled gain sections. Each section has 48 distinct gain steps (+/-48dB of range in 2dB steps) plus MUTE.
As shown in Figure 1, both gain stages have switchable inputs. This switching allows for selection of three different input signals on one channel and two on the other channel. One of the channels also has output switching. In addition to two digitally controlled gain stages, there is a general purpose inverting amplifier. The gain of this amplifier is controlled externally via negative feedback. Control of each gain control section s accomplished through the serial interface. All switching is accomplished using controlled rise and fall times, thereby assuring no transients (clicks or pops).
The MX029 requires a single 5-volt supply and is available in the following packages: 16-pin SOIC (MX029DW), 16-pin CDIP (MX029J), and 24-pin TSSOP (MX029TN).
