Description
The FX/MX019 Digitally Adjustable Amplifier Array is available to replace Communications applications where d.c., voice or data signals need adjustment.
The FX/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, whilst 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.
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 during development, production/calibration and operations.
