Analog Performance (CHOP = 0) or
Channel Throughput (CHOP = 1) 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 fullydifferential 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. …
