Synchronous Sampling ADC GX7606 Replaces AD7606 in Industrial Automation Control Systems

ADCs are generally used to collect various physical quantities from industrial sites, such as analog signals output from pressure sensors, temperature sensors, and so on. These analog signals are quickly and accurately converted to digital signals by ADC for processing and analysis by the control system. In addition, the high-precision ADC can realize the detection of motor operation status and collect parameters such as current and voltage to provide data support for the precise control of the motor.

GXSC GX7606 is an eight-channel 16-bit 200kSPS ADC, commonly used in industrial motorized control systems, the GX7606 can be 100% compatible with the hardware and software to replace ADI‘s AD7606, the chip supports synchronous sampling, and each channel has a built-in analog input clamping protection, analog filter, programmable gain amplifier.

GX7606 integrated digital filter, 3.5ppm / ℃ low drift 2.5V precision reference voltage source and 4.5V reference voltage buffer, support for parallel and serial interfaces. In industrial process control, real-time acquisition and feedback of various parameters help to realize precise control regulation.

Powered by a single 5V power supply, the GX7606 offers throughput rates up to 200kSPS for all 8 channels, supports ±10V and ±5V true bipolar input ranges, 1MΩ analog input impedance, input clamping protection up to ±30V, and an ESD rating of up to 8kV. For applications requiring lower throughput rates, the GX7606‘s built-in oversampling mode and flexible digital filters can be used to improve noise performance. For applications requiring lower throughput rates, the GX7606‘s built-in oversampling mode and flexible digital filters can be used to improve noise performance.
