AD7708BRZ

模数转换器 - ADC 16-Bit 8/10-Ch Low Vtg Low Pwr

8-/10-Channel, Low Voltage,  Low Power,
- ADCs

GENERAL DESCRIPTION AD7708BRZ

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.
