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:

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.
