Brief Description

The FX009A Digitally Adjustable Amplifier Array is

intended to replace trimmer potentiometers and volume

controls in Cellular, PMR, Telephony and

This product replaces the need for manual trimming of

audible signals by using the host microprocessor to

digitally control the set-up of all audio levels.

Communications applications where d.c., voice or data

signals need adjustment.

Applications include:

(i) Control, adjustment and set-up of communications

equipment by an Intelligent ATE without manual

intervention – eg. Deviation, Microphone and L/S

Level, Rx Audio Level etc.

The FX009A is a low-noise single-chip LSI consisting

eight digitally controlled amplifier stages, each with 15

distinct gain/attenuation steps. Control of each

individual amplifier is by an 8-bit serial data stream.

Seven of the amplifier stages offer a +/-3dB range in

steps of 0.43dB, whilst the remaining amplifier offers a

+/-14dB range in steps of 2dB, and is intended for

volume control applications. Each amplifier includes a

16th 'Mute' state which sets the output to bias (V_DD/2)

and powersaves the entire section. Minimum current

drain may be achieved by muting all eight sections.

(ii) Automatic Dynamic Compensation of drift caused

by variations in temperature, linearity, etc.

(iii)Fully automated servicing and re-alignment.

The FX009A is a low-power, single 5-volt CMOS

device available in both 24-pin DIL and SMD package

versions.
