GENERAL DESCRIPTION

The AD73460’s DSP engine combines the ADSP-2100 family

base architecture (three computational units, data address gen-

erators, 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.

The AD73460 is a six-input channel analog front-end processor

for general-purpose applications including industrial power meter-

ing or multichannel analog inputs. It features six 16-bit A/D

conversion channels, each of which provides 72 dB signal-to-noise

ratio over a dc-to-2 kHz signal bandwidth. Each channel also

features a programmable input gain amplifier (PGA) with gain

settings in eight stages from 0 dB to 38 dB.

The AD73460-80 integrates 80K bytes of on-chip memory

configured as 16K words (24-bit) of program RAM and 16K

(16-bit) of data RAM. The AD73460-40 integrates 40K bytes

of on-chip memory configured as 8K words (24-bit) of program

RAM and 8K (16-bit) of data RAM. Power-down circuitry is

also provided to meet the low power needs of battery-operated

portable equipment. The AD73460 is available in a 119-ball

PBGA package.

The AD73460 is particularly suitable for industrial power metering

as each channel samples synchronously, ensuring that there is

no (phase) delay between the conversions. The AD73460 also

features low group delay conversions on all channels.

An on-chip reference voltage of 1.25 V is included. The sampling

rate of the device is programmable with separate settings

offering 64 kHz, 32 kHz, 16 kHz, and 8 kHz sampling rates (from

a master clock of 16.384 MHz), while the serial port (SPORT2)

allows easy expansion of the number of input channels by cas-

cading an extra AFE external to the AD73460.
