AD7708 AD7718 a 8-/10-Channel, Low Voltage, Low Power, - ADCs AD7708/AD7718 FEATURE GENERAL DESCRIPTION 8-/10-Channel, High Resolution - ADCs The AD7708/AD7718 are complete analog front-ends for low AD7708 Has 16-Bit Resolution frequency measurement applications. The AD7718 contains a AD7718 Has 24-Bit Resolution 24-bit Σ-? ADC with PGA and can be configured as 4/5 fully- Factory-Calibrated differential input channels or 8/10 pseudo-differential input Single Conversion Cycle Setting channels. Two pins on the device are configurable as analog Programmable Gain Front End inputs or reference inputs. The AD7708 is a 16-bit version of Simultaneous 50 Hz and 60 Hz Rejection the AD7718. Input signal ranges from 20 mV to 2.56 V can be VREF Select? Allows Absolute and Ratiometric directly converted using these ADCs. Signals can be converted Measurement Capability directly from a transducer without the need for signal conditioning. Operation Can Be Optimized for The device operates from a 32 kHz crystal with an on-board PLL Analog Performance (CHOP = 0) or generating the required internal operating fr
