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...
