Six-Input Channel Analog Front End With DSP

The AD73460 is a six-input channel Analog front-end processor for general-purpose applications including industrial power metering or multi-channel 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 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 cascading an extra AFE external to the AD73460.
The AD73460 '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. 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.
