T he AD73411 is a single-device incorporating a single analog
front end and a microcomputer optimized for digital signal
processing (DSP) and other high speed numeric processing
applications.
T he AD73411’s analog front end (AFE) section is suitable
for general purpose applications including speech and
telephony. T he AFE section features a 16-bit A/D converter
and a 16-bit D/A converter. Each converter provides 77 dB
signal-to-noise ratio over a
voiceband signal bandwidth.
T he AD73411 is particularly suitable for a variety of applica-
tions in the speech and telephony area including low bit rate,
high quality compression, speech enhancement, recognition
and synthesis. T he low group delay characteristic of the AFE
makes it suitable for single or multichannel active control
applications. T he A/D and D/A conversion channels feature
programmable input/ouput gains with ranges 38 dB and 21
dB respectively. An on-chip reference voltage is included
to allow single supply operation.

T he sampling rate of the AFE is programmable with four
separate settings offering 64, 32, 16 and 8 kHz sampling rates
(from a master clock of 16.384 MHz) while the serial port
(SPORT 2) allows easy expansion of the number of I/O
channels by cascading extra AFEs external to the AD73411.
T he AD73411’s DSP engine combines the ADSP-2100
family base architecture (three computational units, data
address generators and a program sequencer) with two serial
ports, a 16-bit internal DMA port, a byte DMA port, a
programmable timer, Flag I/O, extensive interrupt capabilities
and on-chip program and data memory.
T he AD73411-80 integrates 80K bytes of on-chip memory
configured as 16K words (24-bit) of program RAM, and 16K
words (16-bit) of data RAM. T he AD73411-40 integrates
40K bytes of on-chip memory configured as 8K words (24-
bit) of program RAM, and 8K words (16-bit) of data RAM.
Power-down circuitry is also provided to meet the low power
needs of battery operated portable equipment. T he AD73411
is available in a 119-ball PBGA package.
