GENERAL DESCRIPTION
The AD7708/AD7718 are complete analog front-ends for low
frequency measurement applications. The AD7718 contains a
24-bit Σ-∆ ADC with PGA and can be configured as 4/5 fully-
differential input channels or 8/10 pseudo-differential input
channels. Two pins on the device are configurable as analog
inputs or reference inputs. The AD7708 is a 16-bit version of
the AD7718. Input signal ranges from 20 mV to 2.56 V can be
directly converted using these ADCs. Signals can be converted
directly from a transducer without the need for signal conditioning.
The device operates from a 32 kHz crystal with an on-board PLL
generating the required internal operating frequency. The output
data rate from the part is software programmable. The peak-to-
peak resolution from the part varies with the programmed gain
and output data rate.
The part operates from a single 3 V or 5 V supply. When operating
from 3 V supplies, the power dissipation for the part is 3.84 mW typ.
Both parts are pin-for-pin compatible allowing an upgradable
path from 16 to 24 bits without the need for hardware modifica-
tions. The AD7708/AD7718 are housed in 28-lead SOIC and
TSSOP packages.
