AD7708BRUZ Datasheet PDF - ADI

●The AD7708BRUZ is a complete analog front-ends sigma-delta Analog-to-Digital Controller for low frequency measurement applications. The AD7718 contains a 16-bit 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. Input signal ranges from 20mV to 2.56V 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 32kHz 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.
