GXSC GX7190 Compatible AD7190 for High Precision Voltage Acquisition

High-precision voltage signal acquisition circuit is a commonly used functional module in electronic systems, the circuit design is divided into three modules: data acquisition, data processing and display module. Data acquisition generally requires high-precision ADC to convert weak voltage signals into digital signals, GXSC GX7190 can be 100% compatible with AD7190, can be directly replaced in situ and reduce production costs.

 

The GX7190 integrates a programmable gain amplifier (PGA) to provide a high accuracy measurement solution for bridge sensors, thermocouples and resistance temperature devices (RTDs). It is a low noise, low drift and high resolution 24-bit ADC. the main application advantages are as follows:

 

1, high-precision voltage acquisition: GX7190 is able to capture very small voltage changes in voltage acquisition, which is suitable for scenarios that require high-precision voltage measurement, such as battery voltage monitoring, sensor signal acquisition, etc.

2、Multi-channel Voltage Acquisition: GX7190 supports multi-channel input and can acquire multiple voltage signals at the same time, which is suitable for the scenarios that need to monitor the voltages of multiple points at the same time, such as multi-channel power supply voltage monitoring, multi-point temperature measurement and so on.

3, low noise voltage acquisition: GX7190‘s low noise characteristics enable it to accurately collect voltage signals in noisy environments, suitable for noise-sensitive application scenarios, such as medical equipment, precision instruments and so on.

4, programmable gain: GX7190 programmable gain selection from 1, 2, 4, 8, 16, 32, 64 and 128, can be adjusted according to the size of the input signal gain, thus improving the measurement range and accuracy, suitable for input signal dynamic range of the scene.

5, GX7190 can be 100% replacement of AD7190 in hardware and software, GXSC can provide stable supply channels and technical support.
