CONTROLLED AUDIO OUTPUT LINES
The MX019 Digitally Adjustable Amplifier Array replaces trimmer potentiometers and volume controls in
Cellular, LMR, Telephony and Communication applications where voice or data signals need adjustment.
The MX019 is a single-chip LSI consisting of four digitally controlled amplifier stages, each with 15 distinct
gain/attenuation steps. Control of each individual amplifier is by an 8-bit serial data stream. Three of the
amplifier stages offer a 3dB range in steps of 0.43dB, while the remaining amplifier offers a 14dB range in
steps of 2dB, and is suggested for volume control applications. Each amplifier includes a 16th 'Off' state
which, when applied, mutes the output audio from that channel. This array uses a Chip Select input to select
one of two MX019s in a system. The MX019 uses the host microprocessor to digitally control the set-up of all
audio levels during development, production/calibration, and operation. Such applications include:
1. Control, adjustment, and set-up of communications equipment by an Intelligent ATE without manual
intervention – eg. Deviation, Microphone and L/S Levels, RX Audio Level etc.
2. Automatic Dynamic Compensation of drift caused by variations in temperature, linearity, etc.
3. Fully automated servicing and re-alignment.
The MX019 is a low-power, single 5-volt CMOS device available in 24-pin TSSOP (MX019TN), 16-pin SOIC
(MX019DW), 16-pin CDIP (MX019J) and 16-pin PDIP (MX019P) package versions.

Notes:
1. Channel Amplifiers 1 to 4 are inverting amplifiers.
2. Analog input capacitors C1 to C4 are only required for AC input signals, DC input signals do not
require these components.
4. General Description
4.1 Control Data and Timing
The gain of each amplifier block (Channel 1 to Channel 4) in the MX019 is set by a separate 8-bit data word
(bit 7 to bit 0). This 8-bit word, consisting of 4 Address bits (bit 7 to bit 4) and 4 Gain Control bits (bit 3 to bit
0), is loaded to the Control Data Input in serial format using the external data clock.
4.1.1 Data Loading
The 8-bit data word is loaded bit 7 first and bit 0 last.
Bit 7 must be a logic “1” to address the chip.
If bit 7 in the word is a logic “0” that 8-bit word will not be executed. The Chip Address input permits the use of
two devices in a system by indicating to the chip what its address is, a “1” or a “0.” Bit 6 in the address section
of the control word is then used to select which device is being controlled. Figure 3 shows the timing
information required to load and operate this device.
Data is loaded to the MX019 on the rising edge of the Serial Clock. Loaded data is executed on the falling
(rising) edge of the Load/ Latch ( Load /Latch) pulse.
Table 1 shows the format of each 4-bit Address word, Table 2 shows the format of each Gain Control word
with Figure 3 describing the data loading operation and timing.
