GX1248 is 100% Compatible with ADS1248 to Help Industry Achieve Ultra-High Precision Analog Performance

The new 24-bit Ʃ-Δ low power, low noise, complete analog front-end GX1248 is 100% compatible with the replacement ADS1248 to help industry achieve ultra-high precision analog performance. The GX1248 not only achieves ultra-high precision analog performance, but also integrates a complete analog link module including a 12-channel analog switch, a low-noise PGA, a low temperature-drift reference source, high-matching IDAC and high-precision Ʃ-Δ type ADC.

The GX1248 has very high initial accuracy, which can effectively solve the user‘s difficulties in realizing ultra-high accuracy and system calibration, and at the same time effectively simplify the peripheral circuits, reduce PCB size and save costs. The GX1248 is completely designed and developed independently, with 100% intellectual property rights, and its performance and integration degree have reached the international advanced level, which can be widely used in temperature, pressure, flow measurement in factory automation and process control applications, as well as voltage and current measurement in all kinds of precision instruments and equipments.

Thermocouple and RTD (Resistance Temperature Detector) Applications:

Thermocouples have very high temperature measurement range (e.g. 2300℃) and fast response speed, RTDs have higher temperature measurement accuracy and stability, so thermocouples and RTDs (Resistance Temperature Detectors) are commonly used temperature sensors in industrial applications.GX1248, with its high-precision, highly integrated product architecture, can be used as a single-chip to support thermocouple temperature measurement and cold-end compensation such as RTDs or NTCs. The GX1248, with its high accuracy and highly integrated product architecture, can support thermocouple temperature measurement and cold end compensation such as RTD or NTC on a single chip, or can be used individually for any type of RTD (2-wire, 3-wire or 4-wire).
