GX7683 (Replaces AD7683) for Remote Data Acquisition System

When performing data acquisition, there are remote data acquisition systems due to the synchronization of information that needs to be measured at a remote location and then transmitted. Remote data acquisition systems need to obtain accurate environmental information, the system generally to provide multiple acquisition channels for high-speed sampling, the acquisition accuracy and rate becomes an important indicator to measure the performance of the system. This paper recommends 16-bit ADC GX7683 for remote data acquisition system.

16-bit ADC GX7683 by a reference input voltage after resistor-capacitor filtering noise into the power supply interface to power supply, +in and -in input pin input differential information; its basic performance: 16-bit ADC, can achieve a sampling rate of 100kHz and in the 100kHz data rate under the power consumption of 1.8mW, in the 10kHz data rate, the average power consumption of less than The GX7683 supports synchronous serial (SPI/SSI compatible) interface and differential inputs.

The GX7683 also features operation from 2V to 5.25V, synchronous serial (SPI/SSI compatible) interface and differential inputs. The reference voltage can be set to any level in the 500mV to VCC range. Ultra-low power and small size make the GX7683 ideal for portable and battery-operated systems. It is also well suited for remote data acquisition modules, simultaneous multi-channel systems, and isolated data acquisition.The GX7683 is available in an 8-pin VSSOP package.

In summary, the GX7683 is ideally suited for remote data acquisition modules, simultaneous multi-channel systems, and isolated data acquisition, and can be used as a replacement for the AD7683, with full technical support from GXSC.
