GXSC eight channel 64ksps 24 bit GX131E08 chip software and hardware replacement ADS131E08 for industrial power monitoring and protection applications

The stable operation of industrial power supply is directly related to production safety and equipment lifespan in core infrastructure such as factory automation, intelligent manufacturing, and communication base stations. Industrial power supplies need to simultaneously monitor input/output voltage, current, power and other parameters, and respond quickly in the event of overvoltage, overcurrent, overheating, short circuit and other faults to avoid equipment damage or production interruption. Traditional monitoring methods are difficult to meet the needs of high-end industrial scenarios due to insufficient accuracy, delayed response, or weak anti-interference ability.

The high precision, fast speed, and strong anti-interference characteristics of the GXSC GX131E08 chip fully meet the needs of industrial power monitoring, solving the problems of insufficient accuracy and delayed response in traditional monitoring solutions.

Multi channel synchronous sampling and high precision: GX131E08 integrates 8 differential input channels, supports 24 bit ∑ - Δ ADC synchronous sampling, and can run at a data rate of up to 64kSPS. Each channel has a flexible input multiplexer, which is independently connected to generate signals internally for testing, temperature, and fault detection. Fault detection can be performed internally within the device, and GX131E08 uses an integrated comparator with trigger levels controlled by a digital to analog converter.

High anti-interference and wide dynamic range: GX131E08 has excellent dynamic range of 120dB at 1kSPS, crosstalk of -125dB, and total harmonic distortion of -108dB at 50Hz and 60Hz. With the wide dynamic range of ADC, scalable data transmission rate, and internal fault detection, GX131E08 has been favored for industrial power monitoring and protection, as well as testing and measurement applications.

High integration and excellent performance: GX131E08 has a built-in programmable gain amplifier (PGA), internal reference, and onboard oscillator. With high integration and excellent performance, this analog front-end chip can create upgradable industrial power systems while greatly reducing size, power consumption, and overall cost.
